-[Beautify](https://github.com/einars/js-beautify) HTML, CSS and Javascript in Atom.
+> [Beautify](https://github.com/einars/js-beautify)
+HTML (including [Handlebars](http://handlebarsjs.com/)),
+CSS (including [Sass](http://sass-lang.com/) and [LESS](http://lesscss.org/))
+and JavaScript in Atom.
 
-*Attention*: A different package with a similar name exist. Maybe you want to visit this one: [Beautifier](https://atom.io/packages/atom-beautifier).
+## Language Support
+
+- JavaScript
+- HTML, including
+  - [Handlebars](http://handlebarsjs.com/)
+  - XML is supported as an *experimental feature*.
+- CSS, including
+  - [Sass](http://sass-lang.com/)
+  - [LESS](http://lesscss.org/)
 
 ## Usage
 
-Open the Command Palette, and type `Beautify`. This will beautify JS, HTML or CSS files. (XML is supported as an experimental feature.) It will only beautify selected text, if a selection is found - if not, the whole file will be beautified.
+Open the [Command Palette](https://github.com/atom/command-palette), and type `Beautify`.
+
+It will only beautify selected text, if a selection is found - if not, the whole file will be beautified.
+
+### Shortcut
 
 You can also type `ctrl-alt-b` as a shortcut or click `Packages > Beautify` in the menu.
 
+### Package Options
+
 You can also choose to beautify on every file save.
 
-You can change the current config by either using `.jsbeautifyrc` for all files or a non-standard variante with settings for every file type. You can see examples of both way inside [`examples/`](https://github.com/donaldpipowitch/atom-beautify/examples)
+
+## Configuration
+
+Edit your `.jsbeautifyrc` file in any of the following locations:
+
+- Same directory as current file
+- Project root  
+`atom-beautify` will recursively look up from the current file's directory to find `.jsbeautifyrc`.
+- Your User's Home directory
+
+**Note**: *Comments are supported in `.jsbeautifyrc` thanks to [strip-json-comments](https://github.com/sindresorhus/strip-json-comments).*
+
+See examples of both way inside [`examples/`](https://github.com/donaldpipowitch/atom-beautify/tree/master/examples)
