 First of all you need to find and get all Bower packages that your application requires using either
 [Bower](http:/bower.io) itself or its substitute [Bowerphp](http://bowerphp.org/) or any other way you prefer.
 Then you need to set `bower.bower_folder.os` setting in your configuration - it should point to `bower_components` folder
- where you have just installed all packages. By default it is suppoused to be located inside ZF2 application root.

 ## Declare packs of Bower packages
 
 Next you need to declare packs of Bower packages you want to use. Each pack is a collection of Bower packages
-which you want ot have in both combined (for deploying) and separated (for debugging) states. To do that you need to set:
+which you want to have in both combined (for deploying) and separated (for debugging) states. To do that you need to set:
 
 * `bower.pack_folder.os` - filesystem folder where all pack files should be located
 * `bower.pack_folder.web` - web path to access all pack files
 * `bower.debug_folder.os` - filesystem folder where all debug package files should be located
 * `bower.debug_folder.web` - web path to access all debug package files
 * `bower.packs.<pack name>.modules` - Bower packages names to form a pack
-
+* `bower.packs.<pack name>.token` - string that will be appended to file path of the pack (to force browser to reload)
+* `bower.debug_mode` - flag that determines if you are currently debugging your app and want each pack content in separate files  
+
+Most configuration options have default values (check `config/module.config.php` for details), so the only thing 
+you have to declare in your ZF2 app config is something like this (sample is in YAML just to make it easier to read):
+
+    bower:
+      debug_mode: false
+      packs:
+        main:

 Beware of hidden dependencies between packages: module does its best to detect package dependencies
 from `bower.json` files but some of them are not declared there (like between `jquery.mousewheel` and `jquery.scrollpane`).
