 ## Resource configuration
 
-Resource configuration is the act of adding a new resources to an application. A resource has a name, which acts as an identifier to be used for URL generation. The name also allows developers to add routes to existing resources. A resource also has a pattern, meant to match against the _PATH_ portion of a _URL_ (the portion following the scheme and port, e.g. _/foo/bar_ in the _URL_ _http://localhost:8080/foo/bar?q=value_). It does not match against the _QUERY_ portion (the portion that follows _?_, e.g. _q=value_ in _http://localhost:8080/foo/bar?q=value_).

 The [_App::route()_][approute] method provides simple way of registering routes. This method adds a single route to application routing table. This method accepts a _path pattern_, _HTTP method_ and a handler function. `route()` method could be called multiple times for the same path, in that case, multiple routes register for the same resource path.
