+```

+Create a git-flow release:
+
+```
+$ git flow release start VERSION_NUMBER
+```
+
+Edit `lib/abraham/version.rb` and increase the version number.
+
+Build the gem and push to Rubygems:
+
+```
+$ rake build
+$ gem push pkg/abraham-VERSION_NUMBER.gem 
+```
+
+Finish the git-flow release and push to GitHub:
+
+```
+$ git flow release finish
+$ git push origin develop
+$ git push origin master
+$ git push --tags
+```
