-## Setup
-
-### Option 1 - Manual
-
-1. Fork and clone the repo
-1. Run `npm install` to install dependencies
-1. Create a branch for your PR with `git checkout -b your-branch-name`
-
-> To keep `master` branch pointing to remote repository and make pull requests from branches on your fork. To do this, run:
->
-> ```sh
-> git remote add upstream https://github.com/excalidraw/excalidraw.git
-> git fetch upstream
-> git branch --set-upstream-to=upstream/master master
-> ```
-
-### Option 2 - CodeSandbox
-
-1. Go to https://codesandbox.io/s/github/excalidraw/excalidraw
-1. Connect your GitHub account
-1. Go to Git tab on left side
-1. Tap on `Fork Sandbox`
-1. Write your code
-1. Commit and PR automatically
-
-## Pull Request Guidelines
-
-Don't worry if you get any of the below wrong, or if you don't know how. We'll gladly help out.
-
-### Title
-
-Make sure the title starts with a semantic prefix:
-
-- **feat**: A new feature
-- **fix**: A bug fix
-- **docs**: Documentation only changes
-- **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
-- **refactor**: A code change that neither fixes a bug nor adds a feature
-- **perf**: A code change that improves performance
-- **test**: Adding missing tests or correcting existing tests
-- **build**: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
-- **ci**: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
-- **chore**: Other changes that don't modify src or test files
-- **revert**: Reverts a previous commit
-
-### Changelog
-
-Add a brief description of your pull request to the changelog located here: [`src/packages/excalidraw/CHANGELOG.md`](src/packages/excalidraw/CHANGELOG.md)
-
-Notes:
-
-- Make sure to prepend to the section corresponding with the semantic prefix you selected in the title
-- Link to your pull request - this will require updating the CHANGELOG _after_ creating the pull request
-
-### Testing
-
-Once you submit your pull request it will automatically be tested. Be sure to check the results of the test and fix any issues that arise.
-
-It's also a good idea to consider if your change should include additional tests. This is highly recommended for new features or bug-fixes. For example, it's good practice to create a test for each bug you fix which ensures that we don't regress the code in the future.
-
-Finally - always manually test your changes using the convenient staging environment deployed for each pull request. As much as local development attempts to replicate production, there can still be subtle differences in behavior. For larger features consider testing your change in multiple browsers as well.

+The app hosted at [excalidraw.com](https://excalidraw.com) is a minimal showcase of what you can build with Excalidraw. Its [source code](https://github.com/excalidraw/excalidraw/tree/master/src/excalidraw-app) is part of this repository as well, and the app features:
 
-## Documentation
+- 📡&nbsp;PWA support (works offline).
+- 🤼&nbsp;Real-time collaboration.
+- 🔒&nbsp;End-to-end encryption.
+- 💾&nbsp;Local-first support (autosaves to the browser).
+- 🔗&nbsp;Shareable links (export to a readonly link you can share with others).
 
-### Shortcuts
+We'll be adding these features as drop-in plugins for the npm package in the future.
 
-You can almost do anything with shortcuts. Click on the help icon on the bottom right corner to see them all.
+## Quick start
 
-### Curved lines and arrows
-
-Choose line or arrow and click click click instead of drag.
-
-### Charts
-
-You can easily create charts by copy pasting data from Excel or just plain comma separated text.
-
-### Translating
-
-To translate Excalidraw into other languages, please visit [our Crowdin page](https://crowdin.com/project/excalidraw). To add a new language, [open an issue](https://github.com/excalidraw/excalidraw/issues/new) so we can get things set up on our end first.
-
-Translations will be available on the app if they exceed a certain threshold of completion (currently 85%).
-
-### Create a collaboration session manually
-
-In order to create a session manually, you just need to generate a link of this form:
+Install the [Excalidraw npm package](https://www.npmjs.com/package/@excalidraw/excalidraw):
 
 ```
-https://excalidraw.com/#room=[0-9a-f]{20},[a-zA-Z0-9_-]{22}
+npm install react react-dom @excalidraw/excalidraw
 ```
 
-#### Example
+or via yarn
 
 ```
-https://excalidraw.com/#room=91bd46ae3aa84dff9d20,pfLqgEoY1c2ioq8LmGwsFA
+yarn add react react-dom @excalidraw/excalidraw
 ```
 
-The first set of digits is the room. This is visible from the server that’s going to dispatch messages to everyone that knows this number.
-
-The second set of digits is the encryption key. The Excalidraw server doesn’t know about it. This is what all the participants use to encrypt/decrypt the messages.
-
-## Shape libraries
-
-Find a growing list of libraries containing assets for your drawings at [libraries.excalidraw.com](https://libraries.excalidraw.com).
-
-## Embedding Excalidraw in your App?
-
-Try out [`@excalidraw/excalidraw`](https://www.npmjs.com/package/@excalidraw/excalidraw). This package allows you to easily embed Excalidraw as a React component into your apps.
-
-## Development
-

-
-#### Docker Compose
-
-You can use docker-compose to work on Excalidraw locally if you don't want to setup a Node.js env.
-
-```sh
-docker-compose up --build -d
-```
-
-### Self-hosting
-
-We publish a Docker image with the Excalidraw client at [excalidraw/excalidraw](https://hub.docker.com/r/excalidraw/excalidraw). You can use it to self-host your own client under your own domain, on Kubernetes, AWS ECS, etc.
-
-```sh
-docker build -t excalidraw/excalidraw .
-docker run --rm -dit --name excalidraw -p 5000:80 excalidraw/excalidraw:latest
-```
-
-The Docker image is free of analytics and other tracking libraries.
-
-**At the moment, self-hosting your own instance doesn't support sharing or collaboration features.**
-
-We are working towards providing a full-fledged solution for self-hosting your own Excalidraw.

+
+This website is built using [Docusaurus 2](https://docusaurus.io/), a modern static website generator.
+
+### Installation
+
+```
+$ yarn
+```
+
+### Local Development
+
+```
+$ yarn start
+```
+
+This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.
+
+### Build
+
+```
+$ yarn build
+```
+
+This command generates static content into the `build` directory and can be served using any static contents hosting service.
+
+### Deployment
+
+Using SSH:
+
+```
+$ USE_SSH=true yarn deploy
+```
+
+Not using SSH:
+
+```
+$ GIT_USER=<Your GitHub username> yarn deploy
+```
+
+If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the `gh-pages` branch.

+# Footer
+
+Earlier we were using `renderFooter` prop to render custom footer which was removed in [#5970](https://github.com/excalidraw/excalidraw/pull/5970). Now you can pass a `Footer` component instead to render the custom UI for footer.

+# LiveCollaborationTrigger
+
+If you implement live collaboration support and want to expose the same UI button as on [excalidraw.com](https://excalidraw.com), you can render the `<LiveCollaborationTrigger/>` component using the [renderTopRightUI](/docs/@excalidraw/excalidraw/api/props#rendertoprightui) prop.
+
+You'll need to supply `onSelect()` to handle opening of your collaboration dialog, but the button will display `appState.collaborators` count provided you have supplied it.
+
+| Prop | Type | Required | Default | Description |
+| --- | --- | --- | --- | --- |
+| `onSelect` | `function` | Yes |  | Handler called when the user clicks on the button |
+| `isCollaborating` | `boolean` | Yes | false | Whether live collaboration session is in effect. Modifies button style. |

+# WelcomeScreen
+
+When the canvas is empty, Excalidraw can show a welcome _splash_ screen with a logo, a few quick action items, and hints explaining what some of the UI buttons do. Once the user picks a tool, or has created an element on the canvas, the welcome screen will disappear.
+
+You can enable this behavior by rendering a `WelcomeScreen` component like this:
+
+```jsx live
+function App() {
+  return (
+    <div style={{ height: "46rem" }}>
+      <Excalidraw>
+        <WelcomeScreen />
+      </Excalidraw>
+    </div>
+  );
+}
+```
+
+You can also customize the welcome screen by passing children to the `WelcomeScreen` component. See below.
+
+## <WelcomeScreen/>
+
+This is the main component. If you render it without any children, we will render the default welcome screen.
+
+You can customize which welcome screen subcomponents are rendered by passing them as children.
+
+The welcome screen consists of two main groups of subcomponents:
+
+1. [WelcomeScreen.Center](#welcomescreencenterlogo).
+2. [WeelcomeScreen.Hints](#welcomescreenhints).
+
+<img
+  src={require("@site/static/img/welcome-screen-overview.png").default}
+  alt="Excalidraw logo: Sketch handrawn like diagrams."
+/>
+
+### Center
+
+`<WelcomeScreen.Center/>` subcomponent is the center piece of the welcome screen, containing the `logo`, `heading`, and `menu`. All three subcomponents are optional, and you can render whatever you wish into the center component.
+
+```jsx live
+function App() {
+  return (
+    <div style={{ height: "500px" }}>
+      <Excalidraw>
+        <WelcomeScreen>
+          <WelcomeScreen.Center>
+            <WelcomeScreen.Center.Logo />
+            <WelcomeScreen.Center.Heading>
+              Welcome Screen Heading!
+            </WelcomeScreen.Center.Heading>
+            <WelcomeScreen.Center.Menu>
+              <WelcomeScreen.Center.MenuItemLink href="https://github.com/excalidraw/excalidraw">
+                Excalidraw GitHub
+              </WelcomeScreen.Center.MenuItemLink>
+              <WelcomeScreen.Center.MenuItemHelp />
+            </WelcomeScreen.Center.Menu>
+          </WelcomeScreen.Center>
+        </WelcomeScreen>
+      </Excalidraw>
+    </div>
+  );
+}
+```
+
+#### Logo
+
+Use the `<WelcomeScreen.Center.Logo/>` to render a logo. By default it renders the Excalidraw logo and name. Supply `children` to customize.
+
+#### Heading
+
+Use the `<WelcomeScreen.Center.Heading/>` to render a heading below the logo. Supply `children` to change the default message.
+
+#### Menu
+
+`<WelcomeScreen.Center.Menu/>` is a wrapper component for the menu items. You can build your menu using the `<WelcomeScreen.Center.MenuItem>` and `<WelcomeScreen.Center.MenuItemLink>` components, render your own, or render one of the default menu items.
+
+The default menu items are:
+
+- `<WelcomeScreen.Center.MenuItemHelp/>` - opens the help dialog.
+
+- `<WelcomeScreen.Center.MenuItemLoadScene/>` - open the load file dialog.
+
+- `<WelcomeScreen.Center.MenuItemLiveCollaborationTrigger/>` - intended to open the live collaboration dialog. Works similarly to [`<LiveCollaborationTrigger>`](/docs/@excalidraw/excalidraw/api/children-components/live-collaboration-trigger) and you must supply `onSelect()` handler to integrate with your collaboration implementation.
+
+#### MenuItem
+
+The `<WelcomeScreen.Center.MenuItem/>` component can be used to render a menu item.
+
+| Prop | Type | Required | Default | Description |
+| --- | --- | --- | --- | --- |
+| `onSelect` | `function` | Yes |  | The handler is triggered when the item is selected. |
+| `children` | `React.ReactNode` | Yes |  | The content of the menu item |
+| `icon` | `JSX.Element` | No |  | The icon used in the menu item |
+| `shortcut` | `string` | No |  | The keyboard shortcut (label-only, does not affect behavior) |
+
+**WelcomeScreen.Center.MenuItemLink**
+
+To render an external link in a menu item, you can use this component.
+
+| Prop | Type | Required | Default | Description |
+| --- | --- | --- | --- | --- |
+| `href` | `string` | Yes |  | The `href` attribute to be added to the `anchor` element. |
+| `children` | `React.ReactNode` | Yes |  | The content of the menu item |
+| `icon` | `JSX.Element` | No |  | The icon used in the menu item |
+| `shortcut` | `string` | No |  | The keyboard shortcut (label-only, does not affect behavior) |
+
+### Hints
+
+These `<WelcomeScreen.Hints.*>` subcomponents render the UI hints. Text of each hint can be customized by supplying `children`.
+
+```jsx live
+function App() {
+  return (
+    <div style={{ height: "500px" }}>
+      <Excalidraw>
+        <WelcomeScreen>
+          <WelcomeScreen.Hints.ToolbarHint>
+            <p> ToolBar Hints </p>
+          </WelcomeScreen.Hints.ToolbarHint>
+          <WelcomeScreen.Hints.MenuHint />
+          <WelcomeScreen.Hints.HelpHint />
+        </WelcomeScreen>
+      </Excalidraw>
+    </div>
+  );
+}
+```
+
+#### MenuHint
+
+`<WelcomeScreen.Hints.MenuHint>` hint subcomponent for the main menu. Supply `children` to customize the hint text.
+
+#### ToolbarHint
+
+`<WelcomeScreen.Hints.ToolbarHint>` hint subcomponent for the toolbar. Supply `children` to customize the hint text.
+
+#### Help
+
+`<WelcomeScreen.Hints.Help>` hint subcomponent for the help dialog. Supply `children` to customize the hint text.

+
+### Storing custom data on Excalidraw elements
+
+Beyond attributes that Excalidraw elements already support, you can store `custom` data on each `element` in a `customData` object. The type of the attribute is [`Record<string, any>`](https://github.com/excalidraw/excalidraw/blob/master/src/element/types.ts#L66) and is optional.
+
+You can use this to add any extra information you need to keep track of.
+
+You can add `customData` to elements when passing them as [`initialData`](/docs/@excalidraw/excalidraw/api/props/initialdata), or using [`updateScene`](/docs/@excalidraw/excalidraw/api/props/ref#updatescene) / [`updateLibrary`](/docs/@excalidraw/excalidraw/api/props/ref#updatelibrary) afterwards.
+
+```js showLineNumbers
+{
+  type: "rectangle",
+  id: "oDVXy8D6rom3H1-LLH2-f",
+  customData: {customId: '162'},
+}
+```
+
+### isCollaborating
+
+This prop indicates if the app is in `collaboration` mode.
+
+### onChange
+
+Every time component updates, this callback if passed will get triggered and has the below signature.
+
+```js
+(excalidrawElements, appState, files) => void;
+```
+
+1. `excalidrawElements`: Array of [excalidrawElements](https://github.com/excalidraw/excalidraw/blob/master/src/element/types.ts#L114) in the scene.
+
+2. `appState`: [AppState](https://github.com/excalidraw/excalidraw/blob/master/src/types.ts#L95) of the scene.
+
+3. `files`: The [BinaryFiles](https://github.com/excalidraw/excalidraw/blob/master/src/types.ts#L64) which are added to the scene.
+
+Here you can try saving the data to your backend or local storage for example.
+
+### onPointerUpdate
+
+This callback is triggered when mouse pointer is updated.
+
+```js
+({ x, y }, button, pointersMap}) => void;
+```
+
+1.`{x, y}`: Pointer coordinates
+
+2.`button`: The position of the button. This will be one of `["down", "up"]`
+
+3.`pointersMap`: [`pointers`](https://github.com/excalidraw/excalidraw/blob/master/src/types.ts#L131) map of the scene
+
+```js
+(exportedElements, appState, canvas) => void
+```
+
+1. `exportedElements`: An array of [non deleted elements](https://github.com/excalidraw/excalidraw/blob/master/src/element/types.ts#L87) which needs to be exported.
+2. `appState`: [AppState](https://github.com/excalidraw/excalidraw/blob/master/src/types.ts#L95) of the scene.
+3. `canvas`: The `HTMLCanvasElement` of the scene.
+
+### onPointerDown
+
+This prop if passed will be triggered on pointer down events and has the below signature.
+
+<pre>
+(activeTool: <a href="https://github.com/excalidraw/excalidraw/blob/master/src/types.ts#L115"> AppState["activeTool"]</a>, pointerDownState: <a href="https://github.com/excalidraw/excalidraw/blob/master/src/types.ts#L424">PointerDownState</a>) => void
+</pre>
+
+### onScrollChange
+
+This prop if passed will be triggered when canvas is scrolled and has the below signature.
+
+```ts
+(scrollX: number, scrollY: number) => void
+```
+
+### onPaste
+
+This callback is triggered if passed when something is pasted into the scene. You can use this callback in case you want to do something additional when the paste event occurs.
+
+<pre>
+(data: <a href="https://github.com/excalidraw/excalidraw/blob/master/src/clipboard.ts#L18">ClipboardData</a>, event: ClipboardEvent &#124; null) => boolean
+</pre>
+
+This callback must return a `boolean` value or a [promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/Promise) which resolves to a boolean value.
+
+In case you want to prevent the excalidraw paste action you must return `false`, it will stop the native excalidraw clipboard management flow (nothing will be pasted into the scene).
+
+### onLibraryChange
+
+This callback if supplied will get triggered when the library is updated and has the below signature.
+
+<pre>
+  (items:{" "}
+  <a href="https://github.com/excalidraw/excalidraw/blob/master/src/types.ts#L200">
+    LibraryItems
+  </a>
+  ) => void | Promise&lt;any&gt;
+</pre>
+
+It is invoked with empty items when user clears the library. You can use this callback when you want to do something additional when library is updated for example persisting it to local storage.
+
+### onLinkOpen
+
+This prop if passed will be triggered when clicked on `link`. To handle the redirect yourself (such as when using your own router for internal links), you must call `event.preventDefault()`.
+
+<pre>
+(element: <a href="https://github.com/excalidraw/excalidraw/blob/master/src/element/types.ts#L114">ExcalidrawElement</a>, 
+ event: CustomEvent&lt;&#123; nativeEvent: MouseEvent }&gt;) => void
+</pre>
+
+Example:
+
+```js showLineNumbers
+const history = useHistory();
+
+// open internal links using the app's router, but opens external links in
+// a new tab/window
+const onLinkOpen: ExcalidrawProps["onLinkOpen"] = useCallback(
+  (element, event) => {
+    const link = element.link;
+    const { nativeEvent } = event.detail;
+    const isNewTab = nativeEvent.ctrlKey || nativeEvent.metaKey;
+    const isNewWindow = nativeEvent.shiftKey;
+    const isInternalLink =
+      link.startsWith("/") || link.includes(window.location.origin);
+    if (isInternalLink && !isNewTab && !isNewWindow) {
+      history.push(link.replace(window.location.origin, ""));
+      // signal that we're handling the redirect ourselves
+      event.preventDefault();
+    }
+  },
+  [history],
+);
+```
+
+### langCode
+
+Determines the `language` of the UI. It should be one of the [available language codes](https://github.com/excalidraw/excalidraw/blob/master/src/i18n.ts#L14). Defaults to `en` (English). We also export default language and supported languages which you can import as shown below.
+
+```js
+import { defaultLang, languages } from "@excalidraw/excalidraw";
+```
+
+| name | type |
+| --- | --- |
+| `defaultLang` | `string` |
+| `languages` | [`Language[]`](https://github.com/excalidraw/excalidraw/blob/master/src/i18n.ts#L15) |
+
+### viewModeEnabled
+
+This prop indicates whether the app is in `view mode`. When supplied, the value takes precedence over *intialData.appState.viewModeEnabled*, the `view mode` will be fully controlled by the host app, and users won't be able to toggle it from within the app.
+
+### zenModeEnabled
+
+This prop indicates whether the app is in `zen mode`. When supplied, the value takes precedence over *intialData.appState.zenModeEnabled*, the `zen mode` will be fully controlled by the host app, and users won't be able to toggle it from within the app.
+
+### gridModeEnabled
+
+This prop indicates whether the shows the grid. When supplied, the value takes precedence over *intialData.appState.gridModeEnabled*, the grid will be fully controlled by the host app, and users won't be able to toggle it from within the app.
+
+### libraryReturnUrl
+
+If supplied, this URL will be used when user tries to install a library from [libraries.excalidraw.com](https://libraries.excalidraw.com).  
+Defaults to *window.location.origin + window.location.pathname*. To install the libraries in the same tab from which it was opened, you need to set `window.name` (to any alphanumeric string) — if it's not set it will open in a new tab.
+
+### theme
+
+This prop controls Excalidraw's theme. When supplied, the value takes precedence over *intialData.appState.theme*, the theme will be fully controlled by the host app, and users won't be able to toggle it from within the app unless *UIOptions.canvasActions.toggleTheme* is set to `true`, in which case the `theme` prop will control Excalidraw's default theme with ability to allow theme switching (you must take care of updating the `theme` prop when you detect a change to `appState.theme` from the [onChange](#onchange) callback).
+
+You can use [`THEME`](/docs/@excalidraw/excalidraw/api/utils#theme) to specify the theme.
+
+### name
+
+This prop sets the `name` of the drawing which will be used when exporting the drawing. When supplied, the value takes precedence over *intialData.appState.name*, the `name` will be fully controlled by host app and the users won't be able to edit from within Excalidraw.
+
+
+### detectScroll
+
+Indicates whether Excalidraw should listen for `scroll` event on the nearest scrollable container in the DOM tree and recompute the coordinates (e.g. to correctly handle the cursor) when the component's position changes. You can disable this when you either know this doesn't affect your app or you want to take care of it yourself (calling the [`refresh()`](#ref) method).
+
+### handleKeyboardGlobally
+
+Indicates whether to bind keyboard events to `document`. Disabled by default, meaning the keyboard events are bound to the Excalidraw component. This allows for multiple Excalidraw components to live on the same page, and ensures that Excalidraw keyboard handling doesn't collide with your app's (or the browser) when the component isn't focused.
+
+Enable this if you want Excalidraw to handle keyboard even if the component isn't focused (e.g. a user is interacting with the navbar, sidebar, or similar).
+
+### autoFocus
+
+This prop indicates whether to `focus` the Excalidraw component on page load. Defaults to false.
+
+### generateIdForFile
+
+Allows you to override `id` generation for files added on canvas (images). By default, an SHA-1 digest of the file is used.
+
+```tsx
+(file: File) => string | Promise<string>
+```
+
+### validateEmbeddable
+
+```tsx
+validateEmbeddable?: boolean | string[] | RegExp | RegExp[] | ((link: string) => boolean | undefined)
+```
+
+This is an optional property. By default we support a handful of well-known sites. You may allow additional sites or disallow the default ones by supplying a custom validator. If you pass `true`, all URLs will be allowed. You can also supply a list of hostnames, RegExp (or list of RegExp objects), or a function. If the function returns `undefined`, the built-in validator will be used.
+
+Supplying a list of hostnames (with or without `www.`) is the preferred way to allow a specific list of domains.

+        }
+) => void
+```
+
+Scroll the nearest element out of the elements supplied to the center of the viewport. Defaults to the elements on the scene.
+
+| Attribute | type | default | Description |
+| --- | --- | --- | --- |
+| target | [ExcalidrawElement](https://github.com/excalidraw/excalidraw/blob/master/src/element/types.ts#L115) &#124; [ExcalidrawElement[]](https://github.com/excalidraw/excalidraw/blob/master/src/element/types.ts#L115) | All scene elements | The element(s) to scroll to. |
+| opts.fitToContent | boolean | false | Whether to fit the elements to viewport by automatically changing zoom as needed. Note that the zoom range is between 10%-100%. |
+| opts.fitToViewport | boolean | false | Similar to fitToContent but the zoom range is not limited. If elements are smaller than the viewport, zoom will go above 100%. |
+| opts.viewportZoomFactor | number | 0.7 | when fitToViewport=true, how much screen should the content cover, between 0.1 (10%) and 1 (100%) |
+| opts.animate | boolean | false | Whether to animate between starting and ending position. Note that for larger scenes the animation may not be smooth due to performance issues. |
+| opts.duration | number | 500 | Duration of the animation if `opts.animate` is `true`. |
+
+## refresh
+
+```tsx
+() => void
+```
+
+Updates the `offsets` for the `Excalidraw` component so that the coordinates are computed correctly (for example the cursor position).
+
+You don't have to call this when the position is changed on page scroll or when the excalidraw container resizes (we handle that ourselves).
+
+For any other cases if the position of excalidraw is updated (example due to scroll on parent container and not page scroll) you should call this API.
+
+## setToast
+
+This API can be used to show the toast with custom message.
+
+```tsx
+({ message: string, closable?:boolean,duration?:number
+  } | null) => void
+```
+
+| Attribute | type | Description |
+| --- | --- | --- |
+| message | string | The message to be shown on the toast. |
+| closable | boolean | Indicates whether to show the closable button on toast to dismiss the toast. |
+| duration | number | Determines the duration after which the toast should auto dismiss. To prevent autodimiss you can pass `Infinity`. |
+
+To dismiss an existing toast you can simple pass `null`
+
+```js
+setToast(null);
+```
+
+## id
+
+The unique id of the excalidraw component. This can be used to identify the excalidraw component, for example importing the library items to the excalidraw component from where it was initiated when you have multiple excalidraw components rendered on the same page as shown in [multiple excalidraw demo](https://codesandbox.io/s/multiple-excalidraw-k1xx5).
+
+## getFiles
+
+<pre>
+  () =>{" "}
+  <a href="https://github.com/excalidraw/excalidraw/blob/master/src/types.ts#L82">
+    files
+  </a>
+</pre>
+
+This API can be used to get the files present in the scene. It may contain files that aren't referenced by any element, so if you're persisting the files to a storage, you should compare them against stored elements.
+
+## setActiveTool
+
+This API has the below signature. It sets the `tool` passed in param as the active tool.
+
+<pre>
+  (tool: <br /> &#123; type:{" "}
+  <a href="https://github.com/excalidraw/excalidraw/blob/master/src/shapes.tsx#L15">
+    SHAPES
+  </a>
+  [number]["value"]&#124; "eraser" &#125; &#124;
+  <br /> &#123; type: "custom"; customType: string &#125;) => void
+</pre>
+
+## setCursor
+
+This API can be used to customise the mouse cursor on the canvas and has the below signature. It sets the mouse cursor to the cursor passed in param.
+
+```tsx
+(cursor: string) => void
+```
+
+## toggleMenu
+
+```tsx
+(type: "library" | "customSidebar", force?: boolean) => boolean;
+```
+
+This API can be used to toggle a specific menu (currently only the sidebars), and returns whether the menu was toggled on or off. If the `force` flag passed, it will force the menu to be toggled either on/off based on the `boolean` passed.
+
+This API is especially useful when you render a custom sidebar using [`renderSidebar`](#rendersidebar) prop, and you want to toggle it from your app based on a user action.
+
+## resetCursor
+
+```tsx
+() => void
+```
+
+This API can be used to reset to default mouse cursor.

+    AppState
+  </a>
+  ) => JSX | null
+</pre>
+
+A function returning `JSX` to render `custom` UI in the top right corner of the app.
+
+```jsx live
+function App() {
+  return (
+    <div style={{ height: "500px" }}>
+      <Excalidraw
+        renderTopRightUI={() => {
+          return (
+            <button
+              style={{

+          );
+        }}
+      />
+    </div>
+  );
+}
+```
+
+## renderCustomStats
+
+A function that can be used to render custom stats (returns JSX) in the `nerd stats` dialog.
+
+![Nerd Stats](../../../../assets/nerd-stats.png)
+
+For example you can use this prop to render the size of the elements in the storage as do in [excalidraw.com](https://excalidraw.com).
+
+```jsx live
+function App() {
+  return (
+    <div style={{ height: "500px" }}>
+      <Excalidraw
+        renderCustomStats={() => (
+          <p style={{ color: "#70b1ec", fontWeight: "bold" }}>
+            Dummy stats will be shown here
+          </p>
+        )}
+      />
+    </div>
+  );
+}
+```
+
+## renderSidebar
+
+```tsx
+() => JSX | null;
+```
+
+You can render `custom sidebar` using this prop. This sidebar is the same that the library menu sidebar is using, and can be used for any purposes your app needs.
+
+You need to import the `Sidebar` component from `excalidraw` package and pass your content as its `children`. The function `renderSidebar` should return the `Sidebar` instance.
+
+### Sidebar
+The `<Sidebar>` component takes these props (all are optional except `children`):
+
+| Prop | Type | Description |
+| --- | --- | --- |
+| `children` | `React.ReactNode` | Content you want to render inside the `sidebar`. |
+| `onClose` | `function` | Invoked when the component is closed (by user, or the editor). No need to act on this event, as the editor manages the sidebar open state on its own. |
+| `onDock` | `function` | Invoked when the user toggles the `dock` button. The callback recieves a `boolean` parameter `isDocked` which indicates whether the sidebar is `docked` |
+| `docked` | `boolean` | Indicates whether the sidebar is`docked`. By default, the sidebar is `undocked`. If passed, the docking becomes controlled, and you are responsible for updating the `docked` state by listening on `onDock` callback. To decide the breakpoint for docking you can use [UIOptions.dockedSidebarBreakpoint](/docs/@excalidraw/excalidraw/api/props/ui-options#dockedsidebarbreakpoint) for more info on docking. |
+| `dockable` | `boolean` | Indicates whether to show the `dock` button so that user can `dock` the sidebar. If `false`, you can still dock programmatically by passing `docked` as `true`. |
+
+The sidebar will always include a header with `close / dock` buttons (when applicable).
+You can also add custom content to the header, by rendering `<Sidebar.Header>` as a child of the `<Sidebar>` component. Note that the custom header will still include the default buttons.
+
+
+### Sidebar.Header
+
+| name | type | description |
+| --- | --- | --- |
+| children | `React.ReactNode` | Content you want to render inside the sidebar header as a sibling of `close` / `dock` buttons. |
+
+To control the visibility of the sidebar you can use [`toggleMenu("customSidebar")`](/docs/@excalidraw/excalidraw/api/props/ref#togglemenu) api available via `ref`.
+
+```tsx live
+function App() {
+  const [excalidrawAPI, setExcalidrawAPI] = useState(null);
+
+  return (
+    <div style={{ height: "500px" }}>
+      <button className="custom-button" onClick={() => excalidrawAPI.toggleMenu("customSidebar")}>
+        Toggle Custom Sidebar
+      </button>
+      <Excalidraw
+        UIOptions={{ dockedSidebarBreakpoint: 100 }}
+        ref={(api) => setExcalidrawAPI(api)}
+        renderSidebar={() => {
+          return (
+            <Sidebar dockable={true}>
+              <Sidebar.Header>Custom Sidebar Header </Sidebar.Header>
+              <p style={{ padding: "1rem" }}> custom Sidebar Content </p>
+            </Sidebar>
+          );
+        }}
+      />
+    </div>
+  );
+}
+```
+
+## renderEmbeddable
+
+<pre>
+  (element: NonDeleted&lt;ExcalidrawEmbeddableElement&gt;, appState: <a href="https://github.com/excalidraw/excalidraw/blob/master/src/types.ts#L95">AppState</a>) => JSX.Element | null
+</pre>
+
+Allows you to replace the renderer for embeddable elements (which renders `<iframe>` elements).
+
+| Parameter | Type | Description |
+| --- | --- | --- |
+| `element` | `NonDeleted<ExcalidrawEmbeddableElement>` | The embeddable element to be rendered. |
+| `appState` | `AppState` | The current state of the UI. |

+# UIOptions
+
+This prop can be used to customise UI of Excalidraw. Currently we support customising [`canvasActions`](#canvasactions), [`dockedSidebarBreakpoint`](#dockedsidebarbreakpoint) and [`welcomeScreen`](#welcmescreen).
+
+<pre>
+  &#123;
+  <br /> canvasActions?: <a href="https://github.com/excalidraw/excalidraw/blob/master/src/types.ts#L372">
+    CanvasActions
+  </a>, <br /> dockedSidebarBreakpoint?: number, <br /> welcomeScreen?: boolean <br />
+
+  }
+</pre>
+
+## canvasActions
+
+This `prop` controls the visibility of the canvas actions inside the `menu`.
+
+| Prop | Type | Default | Description |
+| --- | --- | --- | --- |
+| `changeViewBackgroundColor` | `boolean` | `true` | Indicates whether to show `Background color picker`. |
+| `clearCanvas` | `boolean` | `true` | Indicates whether to show `Clear canvas` button. |
+| `export` | `false` &#124; [`exportOpts`](#exportopts) | `object` | This prop allows to customize the UI inside the export dialog. By default it shows the `save file to disk`. For more details visit [`exportOpts`](#exportopts). |
+| `loadScene` | `boolean` | `true` | Indicates whether to show `Load` button. |
+| `saveToActiveFile` | `boolean` | `true` | Indicates whether to show `Save` button to save to current file. |
+| `toggleTheme` | `boolean` &#124; `null` | `null` | Indicates whether to show `Theme toggle`. When defined as `boolean`, takes precedence over [`props.theme`](/docs/@excalidraw/excalidraw/api/props#theme) to show `Theme toggle`. |
+| `saveAsImage` | `boolean` | `true` | Indicates whether to show `Save as image` button. |
+
+```tsx live
+function App() {
+  const UIOptions = {
+    canvasActions: {
+      changeViewBackgroundColor: false,
+      clearCanvas: false,
+      loadScene: false,
+    },
+  };
+  return (
+    <div style={{ height: "500px" }}>
+      <Excalidraw UIOptions={UIOptions} />
+    </div>
+  );
+}
+```
+
+### exportOpts
+
+The below attributes can be set in `UIOptions.canvasActions.export` to customize the export dialog.  
+If `UIOptions.canvasActions.export` is `false` the export button will not be rendered.
+
+| Prop | Type | Default | Description |
+| --- | --- | --- | --- |
+| `saveFileToDisk` | `boolean` | `true` | Indicates whether `save file to disk` button should be shown |
+| `onExportToBackend` | `object` | \_ | This callback is triggered when the shareable-link button is clicked in the export dialog. The link button will only be shown if this callback is passed. |
+| `renderCustomUI` | `object` | \_ | This callback should be supplied if you want to render custom UI in the export dialog. |
+
+## dockedSidebarBreakpoint
+
+This prop indicates at what point should we break to a docked, permanent sidebar. If not passed it defaults to [`MQ_RIGHT_SIDEBAR_MAX_WIDTH_PORTRAIT`](https://github.com/excalidraw/excalidraw/blob/master/src/constants.ts#L161).  
+If the _width_ of the _excalidraw_ container exceeds _dockedSidebarBreakpoint_, the sidebar will be `dockable` and the button to `dock` the sidebar will be shown  
+If user choses to `dock` the sidebar, it will push the right part of the UI towards the left, making space for the sidebar as shown below.
+

+
+#### languages
+
+List of supported language codes. You can pass any of these to `Excalidraw`'s [`langCode` prop](/docs/@excalidraw/excalidraw/api/props/#langcode).
+
+#### useI18n
+
+A hook that returns the current language code and translation helper function. You can use this to translate strings in the components you render as children of `<Excalidraw>`.
+
+```jsx live
+function App() {
+  const { t } = useI18n();
+  return (
+    <div style={{ height: "500px" }}>
+      <Excalidraw>

+# Customizing Styles
+
+Excalidraw is using CSS variables to style certain components. To override them, you should set your own on the `.excalidraw` and `.excalidraw.theme--dark` (for dark mode variables) selectors.
+
+Make sure the selector has higher specificity, e.g. by prefixing it with your app's selector:
+
+```css
+.your-app .excalidraw {
+  --color-primary: red;
+}
+.your-app .excalidraw.theme--dark {
+  --color-primary: pink;
+}
+```
+
+Most notably, you can customize the primary colors, by overriding these variables:
+
+- `--color-primary`
+- `--color-primary-darker`
+- `--color-primary-darkest`
+- `--color-primary-light`
+- `--color-primary-contrast-offset` — a slightly darker (in light mode), or lighter (in dark mode) `--color-primary` color to fix contrast issues (see [Chubb illusion](https://en.wikipedia.org/wiki/Chubb_illusion)). It will fall back to `--color-primary` if not present.

+# Development
+
+This page relates to developing the `@excalidraw/excalidraw` package itself.
+
+## Example app
+
+To start the example app using the `@excalidraw/excalidraw` package, follow the below steps:
+
+1. Install the dependencies
+
+   ```bash
+   cd src/packages/excalidraw && yarn
+   ```
+
+2. Start the example app
+
+   ```bash
+   yarn start
+   ```
+
+   [http://localhost:3001](http://localhost:3001) will open in your default browser.
+
+   The example is same as the [codesandbox example](https://ehlz3.csb.app/)
+
+## Releasing
+
+### Create a test release
+
+You can create a test release by posting the below comment in your pull request:
+
+```bash
+@excalibot trigger release
+```
+
+Once the version is released `@excalibot` will post a comment with the release version.
+
+### Creating a production release
+
+To release the next stable version follow the below steps:
+
+```bash
+yarn prerelease version
+```
+
+You need to pass the `version` for which you want to create the release. This will make the changes needed before making the release like updating `package.json`, `changelog` and more.
+
+The next step is to run the `release` script:
+
+```bash
+yarn release
+```
+
+This will publish the package.
+
+Right now there are two steps to create a production release but once this works fine these scripts will be combined and more automation will be done.

+# FAQ
+
+### Does this package support collaboration ?
+
+No, Excalidraw package doesn't come with collaboration built in, since the implementation is specific to each host app. We expose APIs which you can use to communicate with Excalidraw which you can use to implement it. You can check our own implementation [here](https://github.com/excalidraw/excalidraw/blob/master/src/excalidraw-app/index.tsx). Here is a [detailed answer](https://github.com/excalidraw/excalidraw/discussions/3879#discussioncomment-1110524) on how you can achieve the same.
+
+### Turning off Aggressive Anti-Fingerprinting in Brave browser
+
+When *Aggressive Anti-Fingerprinting* is turned on, the `measureText` API breaks which in turn breaks the Text Elements in your drawings. Here is more [info](https://github.com/excalidraw/excalidraw/pull/6336) on the same.
+
+We strongly recommend turning it off. You can follow the steps below on how to do so.
+
+
+1. Open [excalidraw.com](https://excalidraw.com) in Brave and click on the **Shield** button
+![Shield button](../../assets/brave-shield.png)
+
+<div style={{width:'30rem'}}>
+
+2. Once opened, look for **Aggressively Block Fingerprinting**
+
+![Aggresive block fingerprinting](../../assets/aggressive-block-fingerprint.png)
+
+3. Switch to **Block Fingerprinting**
+
+![Block filtering](../../assets/block-fingerprint.png)
+
+4. Thats all. All text elements should be fixed now 🎉
+
+</div>
+
+If disabling this setting doesn't fix the display of text elements, please consider opening an [issue](https://github.com/excalidraw/excalidraw/issues/new) on our GitHub, or message us on [Discord](https://discord.gg/UexuTaE).
+

+# Installation
+
+**Excalidraw** is published to npm as a component you can directly embed in your projects.
+
+Using `npm`:
+
+```bash
+npm install react react-dom @excalidraw/excalidraw
+```
+
+or `yarn`:
+
+```bash
+yarn add react react-dom @excalidraw/excalidraw
+```
+
+:::tip
+
+**If you don't want to wait for the next stable release and try out the unreleased changes you can use `@excalidraw/excalidraw@next`.**
+
+:::
+
+### Static assets
+
+Excalidraw depends on assets such as localization files (if you opt to use them), fonts, and others.
+
+By default these assets are loaded from a public CDN [`https://unpkg.com/@excalidraw/excalidraw/dist/`](https://unpkg.com/@excalidraw/excalidraw/dist), so you don't need to do anything on your end.
+
+However, if you want to host these files yourself, you can find them in your `node_modules/@excalidraw/excalidraw/dist` directory, in folders `excalidraw-assets` (for production) and `excalidraw-assets-dev` (for development).
+
+Copy these folders to your static assets directory, and add a `window.EXCALIDRAW_ASSET_PATH` variable in your `index.html` or `index.js` entry file pointing to your public assets path (relative). For example, if you serve your assets from the root of your hostname, you would do:
+
+```js
+window.EXCALIDRAW_ASSET_PATH = "/";
+```
+
+### Dimensions of Excalidraw
+
+Excalidraw takes _100%_ of `width` and `height` of the containing block so make sure the container in which you render Excalidraw has non zero dimensions.
+
+### Demo
+
+[Try here](https://codesandbox.io/s/excalidraw-ehlz3).

+# Integration
+
+## Module bundler
+
+If you are using a module bundler (for instance, Webpack), you can import it as an ES6 module as shown below
+
+```js
+import { Excalidraw } from "@excalidraw/excalidraw";
+```
+
+:::info
+
+Throughout the documentation we use live, editable Excalidraw examples like the one shown below.
+
+While we aim for the examples to closely reflect what you'd get if you rendered it yourself, we actually initialize it with some props behind the scenes.  
+For example, we're passing a `theme` prop to it based on the current color theme of the docs you're just reading.
+
+:::
+
+```jsx live
+function App() {
+  return (
+    <>
+      <h1 style={{ textAlign: "center" }}>Excalidraw Example</h1>
+      <div style={{ height: "500px" }}>
+        <Excalidraw />
+      </div>
+    </>
+  );
+}
+```
+
+### Rendering Excalidraw only on client
+
+Since _Excalidraw_ doesn't support server side rendering, you should render the component once the host is `mounted`.
+
+The following worfklow shows one way how to render Excalidraw on Next.js. We'll add more detailed and alternative Next.js examples, soon.
+
+```jsx showLineNumbers
+import { useState, useEffect } from "react";
+export default function App() {
+  const [Excalidraw, setExcalidraw] = useState(null);
+  useEffect(() => {
+    import("@excalidraw/excalidraw").then((comp) => setExcalidraw(comp.Excalidraw));
+  }, []);
+  return <>{Excalidraw && <Excalidraw />}</>;
+}
+```
+
+The `types` are available at `@excalidraw/excalidraw/types`, you can view [example for typescript](https://codesandbox.io/s/excalidraw-types-9h2dm)
+
+## Browser
+
+To use it in a browser directly:
+
+For development use :point_down:
+
+```js
+<script
+  type="text/javascript"
+  src="https://unpkg.com/@excalidraw/excalidraw/dist/excalidraw.development.js"
+></script>
+```
+
+For production use :point_down:
+
+```js
+<script
+  type="text/javascript"
+  src="https://unpkg.com/@excalidraw/excalidraw/dist/excalidraw.production.min.js"
+></script>
+```
+
+You will need to make sure `react`, `react-dom` is available as shown in the below example. For prod please use the production versions of `react`, `react-dom`.
+
+import Tabs from "@theme/Tabs";
+import TabItem from "@theme/TabItem";

+# Contributing
+
+Pull requests are welcome. For major changes, please [open an issue](https://github.com/excalidraw/excalidraw/issues/new) first to discuss what you would like to change.
+
+We have a [roadmap](https://github.com/orgs/excalidraw/projects/3) which we strongly recommend to go through and check if something interests you.
+For new contributors we would recommend to start with *Easy* tasks.
+
+In case you want to pick up something from the roadmap, comment on that issue and one of the project maintainers will assign it to you, post which you can discuss in the issue and start working on it.
+
+## Setup
+
+### Option 1 - Manual
+
+1. Fork and clone the repo
+1. Run `yarn` to install dependencies
+1. Create a branch for your PR with `git checkout -b your-branch-name`
+
+> To keep `master` branch pointing to remote repository and make pull requests from branches on your fork. To do this, run:
+>
+> ```bash
+> git remote add upstream https://github.com/excalidraw/excalidraw.git
+> git fetch upstream
+> git branch --set-upstream-to=upstream/master master
+> ```
+
+### Option 2 - CodeSandbox
+
+1. Go to https://codesandbox.io/p/github/excalidraw/excalidraw
+1. Connect your GitHub account
+1. Go to Git tab on left side
+1. Tap on `Fork Sandbox`
+1. Write your code
+1. Commit and PR automatically
+
+## Pull Request Guidelines
+
+Don't worry if you get any of the below wrong, or if you don't know how. We'll gladly help out.
+
+### Title
+
+Make sure the title starts with a semantic prefix:
+
+- **feat**: A new feature
+- **fix**: A bug fix
+- **docs**: Documentation only changes
+- **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
+- **refactor**: A code change that neither fixes a bug nor adds a feature
+- **perf**: A code change that improves performance
+- **test**: Adding missing tests or correcting existing tests
+- **build**: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
+- **ci**: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
+- **chore**: Other changes that don't modify src or test files
+- **revert**: Reverts a previous commit
+
+### Changelog
+
+Add a brief description of your pull request to the changelog located here: [changelog](https://github.com/excalidraw/excalidraw/blob/master/CHANGELOG.md)
+
+Notes:
+
+- Make sure to prepend to the section corresponding with the semantic prefix you selected in the title
+- Link to your pull request - this will require updating the CHANGELOG _after_ creating the pull request
+
+### Testing
+
+Once you submit your pull request it will automatically be tested. Be sure to check the results of the test and fix any issues that arise.
+
+It's also a good idea to consider if your change should include additional tests. This is highly recommended for new features or bug-fixes. For example, it's good practice to create a test for each bug you fix which ensures that we don't regress the code in the future.
+
+Finally - always manually test your changes using the convenient staging environment deployed for each pull request. As much as local development attempts to replicate production, there can still be subtle differences in behavior. For larger features consider testing your change in multiple browsers as well.
+
+:::note
+Some checks, such as the `lint` and `test`, require approval from the maintainers to run. 
+They will appear as `Expected — Waiting for status to be reported` in the PR checks when they are waiting for approval.
+:::
+
+## Translating
+
+To translate Excalidraw into other languages, please visit [our Crowdin page](https://crowdin.com/project/excalidraw). To add a new language, [open an issue](https://github.com/excalidraw/excalidraw/issues/new) so we can get things set up on our end first.
+
+Translations will be available on the app if they exceed a certain threshold of completion (currently **85%**).

+
+## Self-hosting
+
+We publish a Docker image with the Excalidraw client at [excalidraw/excalidraw](https://hub.docker.com/r/excalidraw/excalidraw). You can use it to self-host your own client under your own domain, on Kubernetes, AWS ECS, etc.
+
+```bash
+docker build -t excalidraw/excalidraw .
+docker run --rm -dit --name excalidraw -p 5000:80 excalidraw/excalidraw:latest
+```
+
+The Docker image is free of analytics and other tracking libraries.
+
+**At the moment, self-hosting your own instance doesn't support sharing or collaboration features.**
+
+We are working towards providing a full-fledged solution for self-hosting your own Excalidraw.
