 Using plugins and configuration variables, you can modify the way the Talk comment stream behaves. Here are some common configuration options:
 
+
+### Rich Text Editor
+
+To enable our default rich text editor plugin, you'll need to:
+
+1. Enable `talk-plugin-rich-text` as a server-side plugin
+2. Enable `talk-plugin-rich-text-pell` as a client-side plugin
+3. If you have `talk-plugin-comment-content` enabled, you will need to disable this (this supports hyperlinks in the comment body)
+
+Out of the box, our Talk Editor supports Bold, Italic, and Blockquote.
+
+If you want to support another editor, you can create a plugin and replace the client-side one with the editor of your choice.
+
+For more information on our implementation, see https://github.com/coralproject/talk/pull/1391

+You can add your own stylesheet in Admin > Configure > Tech Settings.
+
+If you would like to change the styling of any elements in Talk, we provide global classnames with the prefix `talk-`. The easiest way to find the classname for the element you're looking for is to use the web inspector, and then update your stylesheet accordingly.
+
+Plugins also have their own stylesheets located in the client directory.
