+Use LESS with your Laravel installation. Uses [oyejorge/less.php](http://lessphp.gpeasy.com/) instead of [leafo/lessphp](http://leafo.net/lessphp/) which is a more actively developed port of the official LESS processor.
+
+Use [matthiasmullie/minify](https://github.com/matthiasmullie/minify) for minifying.
 
 ## Features
 - Can modify LESS variables on-the-fly
 - Can parse custom CSS/LESS and append it to the resulting file
 - Works with Twitter Bootstrap v3.3.5 (thanks to oyejorge/less.php)
 - Caching support

+- `never` -- Don't check, don't recompile (best choice on a production server).

+
+Set `LESS_RECOMPILE` in `.env`
+
+````
+LESS_RECOMPILE=change
+````
+
+## Minify
 
+By default, the generated css is not minified. To minify it, just set `LESS_MINIFY` to `true` in `.env`
+
+````
+LESS_MINIFY=true
+````
 
 ## Usage
 
+By default, you must create your `.less` files into `resources/assets/less`
+
 Within your models or controllers, you can perform modification to the outputted CSS. Here are some examples:
 before you perform a redirect...
 
 ```php
 public function recompileCSS()
 {
-    Less::modifyVars(['@body-bg' => 'pink'])->recompile('filename');
-
+    Less::modifyVars(['@body-bg' => 'pink'])->recompile('filename_wo_ext');
     return Redirect::back();
 }
 ```
 
 Within your view you can use the `Less::url()` function to link to your generated CSS
 
 ```html
-	<link href="{!! Less::url('filename') !!}" rel="stylesheet" />
+	<link href="{!! Less::url('filename_wo_ext') !!}" rel="stylesheet" />
 ```
 
-Passing `true` as the second parameter to `Less::url()` will auto-detect, based on your configuration, if recompilation is needed and will do so accordingly. 
+If necessary, passing `false` as second parameter to `Less::url()` will avoid all recompilation (already if you set `LESS_RECOMPILE` to `always`).
 
 ## Credits
 This project is inspired by [Less4Laravel](https://github.com/jtgrimes/less4laravel).
 Without the hard work of [oyejorge/less.php](http://lessphp.gpeasy.com/) this project wouldn't be possible.
