 Every application follows the same flow:
 
-1. Application starts from `index.php`
-2. Includes `APPPATH/bootstrap.php`
-3. The bootstrap calls [Kohana::modules] with a list of modules to use
-    1. Generates an array of paths for the cascading filesystem
-    2. Checks each module to see if it has an init.php, and if it does, loads it
-	    * Each init.php can define a series of routes to use, they are loaded when the init.php file is included
-4. [Request::instance] called to process the request
-    1. Checks each route until a match is found
-    2. Loads controller and passes the request to it
-    3. Calls the [Controller::before] method
-    4. Calls the controller action
-    5. Calls the [Controller::after] method
-5. Displays the [Request] response
-
-The controller action can be changed by [Controller::before] based on the request parameters.
+1. Application starts from `index.php`.
+2. The application, module, and system paths are set.
+3. Error reporting levels are set.
+4. Install file is loaded, if it exists.
+5. The [Kohana] class is loaded.
+6. The bootstrap file, `APPPATH/bootstrap.php`, is included.
+7. [Kohana::init] is called, which sets up error handling, caching, and logging.
+8. [Kohana_Config] readers and [Kohana_Log] writers are attached.
+9. [Kohana::modules] is called to enable additional modules.
+    * Module paths are added to the [cascading filesystem](about.filesystem).
+    * Includes the module `init.php` file, if it exists. 
+    * The `init.php` file can perform additional environment setup, including adding routes.
+10. [Route::set] is called multiple times to define the [application routes](using.routing).
+11. [Request::instance] called to start processing the request.
+    1. Checks each route that has been set until a match is found.
+    2. Creates the controller instance and passes the request to it.
+    3. Calls the [Controller::before] method.
+    4. Calls the controller action, which generates the request response.
+    5. Calls the [Controller::after] method.
+        * The above 5 steps can be repeated multiple times when using [HMVC sub-requests](about.mvc).
+12. The main [Request] response is displayed
