Syntaxhighlighter support

@@ -20,6 +20,14 @@ Examples:
  * `[gist id=546764 file=file.txt bump=1]`
  * `[gist]http://gist.github.com/546764[/gist]`
 
+This plugin also supports using [SyntaxHighlighter Evolved](http://wordpress.org/plugins/syntaxhighlighter/)
+for highlighting rather then the default gist mockup. **NOTE** for this to work, the following line must be added to the top
+of the wp-settings.php file located in the root of your wordpress install: `define('EMBED_GISTHUB_SYNTAXHIGHLIGHTER', true);`.
+Also, in the SyntaxHighlighter Evolved Settings (inside wp-admin), the "Load All Brushes" checkbox must be enabled.
+
+Example Usage:
+ * `[gist id=546764 highlight=she]`

 Cache is implemented with the Transients API to minimize delay on loading
 content. Default TTL (time to live) is 86400 seconds or one day.
