 ### Multiple routes matches? Which one has the priority?
 
-The router will match routes in the order they're added.
+The router will match routes in the order they're added and will render multiple routes, if they match.
 
-It's possible to render multiple routes.

-If you want the router to stop when a route is matched, you simply return a value in your callback or stop the execution manually (using `response()->json()` etc.). 
+If you want the router to stop when a route is matched, you simply return a value in your callback or stop the execution manually (using `response()->json()` etc.) or simply by returning a result.
 
 Any returned objects that implements the `__toString()` magic method will also prevent other routes from being rendered. 
 
+If you want the router only to execute one route per request, you can [disabling multiple route rendering](#disable-multiple-route-rendering).
+
 ### Using the router on sub-paths
 
-Using the library on a sub-path like `localhost/project/` is not officially supported, however it is possible to get it working quite easily.
-
-Add an event that appends your sub-path when a new loadable route is added.
-
-**Example:**
-
-```php
-// ... your routes.php file
-
-if($isRunningLocally) {
-
-    $eventHandler = new EventHandler();
-    $eventHandler->register(EventHandler::EVENT_ADD_ROUTE, function (EventArgument $arg) use (&$status) {
-
-        if ($arg->route instanceof \Pecee\SimpleRouter\Route\LoadableRoute) {
-            $arg->route->prependUrl('/local-path');
-        }
-
-    });
-
-    TestRouter::addEventHandler($eventHandler);
