 Most of the packages are in there to try to match what the OSF wiki is doing. The two exceptions being markdown-it-highlightjs.js and markdown-it-mathjax.js. The highlighter matches the functionality of what is on the osf however, and the markdown-it-mathjax.js increases functionality with mathjax.

 To add a new library, you need to make sure its loadable in md.js somehow, either through exporting via `root.<name>` or some other means. Some of the markdown plugins added have custom code in them to load them into `root`.
 
 Libraries should try to use the same version as the ones used on the OSF. The plugins do not matter as much, but `markdown-it` and `Mathjax` you should try to match exactly because styling can change between versions.
 
 To add a new library that is not already set up to export to `root` can be a bit tricky, but the gist of it is, wrap the plugin in this code:
 
-```
+```javascript
 ;(function (root, factory) {
-  if (typeof exports === 'object') {
-    module.exports = factory()
+    if (typeof exports === 'object') {
+        module.exports = factory()
   } else {
-    root.<PLUGIN_NAME> = factory()
-  }
+        root.<PLUGIN_NAME> = factory()
+    }
 })(this, function () {
 
 
-return function(md){
+    return function(md){
 
-    .....
-}
+        .....
+    }
 
 })
 ```
 
 And then modify it to work in this context. See other plugins for examples.
 
-Then, in md.js, you can add a plugin to the markdown renderer by adding a `.use(<window.<PLUGIN_NAME>)`
