 ## Examples
 
+### Imports, Raw, and Comment
+
+The ability to import other groocss files is supported by importFile, importStream, and importString methods which take
+a parameter map and input. For example:
+
+    importFile otherCss.absoluteFile, linkColor: '#456789'
+
+This would allow you to make a "template file" for example with variables replaced in multiple ways.
+
+There are also "raw" and "comment" commands, for including raw CSS and comments respectively.
