 `TwigExtension` provides these functions to your Twig templates:
 
-* `path_for()` - returns the URL for a given route.
-* `base_url()` - returns the `Uri` object's base URL.
-* `is_current_path()` - returns true is the provided route name and parameters are valid for the current path.
-* `current_path()` - renders the current path, with or without the query string.
+* `url_for()` - returns the URL for a given route. e.g.: /hello/world
+* `full_url_for()` - returns the URL for a given route. e.g.: http://www.example.com/hello/world
+* `is_current_url()` - returns true is the provided route name and parameters are valid for the current path.
+* `current_url()` - returns the current path, with or without the query string.
+* `get_uri()` - returns the `UriInterface` object from the incoming `ServerRequestInterface` object
