 - **autoDownloadFontAwesome**: If set to `true`, force downloads Font Awesome (used for icons). If set to `false`, prevents downloading. Defaults to `undefined`, which will intelligently check whether Font Awesome has already been included, then download accordingly.
 - **autofocus**: If set to `true`, autofocuses the editor. Defaults to `false`.

-#### Toolbar icons

+### Toolbar icons
 
 Below are the built-in toolbar icons (only some of which are enabled by default), which can be reorganized however you like. "Name" is the name of the icon, referenced in the JS. "Action" is either a function or a URL to open. "Class" is the class given to the icon. "Tooltip" is the small tooltip that appears via the `title=""` attribute. Note that shortcut hints are added automatically and reflect the specified action if it has a keybind assigned to it (i.e. with the value of `action` set to `bold` and that of `tooltip` set to `Bold`, the final text the user will see would be "Bold (Ctrl-B)").

 ## How it works
+
 EasyMDE is a continuation of SimpleMDE.
 
 SimpleMDE began as an improvement of [lepture's Editor project](https://github.com/lepture/editor), but has now taken on an identity of its own. It is bundled with [CodeMirror](https://github.com/codemirror/codemirror) and depends on [Font Awesome](http://fontawesome.io).
 
 CodeMirror is the backbone of the project and parses much of the Markdown syntax as it's being written. This allows us to add styles to the Markdown that's being written. Additionally, a toolbar and status bar have been added to the top and bottom, respectively. Previews are rendered by [Marked](https://github.com/chjj/marked) using GFM.

 ## SimpleMDE fork
 
 I originally made this fork to implement FontAwesome 5 compatibility into SimpleMDE. When that was done I submitted a [pull request](https://github.com/sparksuite/simplemde-markdown-editor/pull/666), which has not been accepted yet. This, and the project being inactive since May 2017, triggered me to make more changes and try to put new life into the project.
