 Painless static file handling for Rack apps.
 
 - Automatically configures `Rack::Static` by default.
 - Glob and inject JavaScript/CSS files into served HTML.
+  - Inserts CSS before `</head>` and JS before `</body>` by default.
+  - Change the inject mode to use placeholder slots instead.
 
 # Usage

 <!-- index.html //-->
 
 <!doctype html>
