+Excluding a path from lookup
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You might want to prefix some controllers in a specific folder with a uri. To
+do this, you would need a different configuration for your general controllers
+and the controllers in this folder.
+
+In that case, you can use the ``exclude`` keyword to exclude a path from being
+looked up to avoid duplicate routes. To make sure that the exclude parameter is 
+taken into account, you will also need to add a ``*`` character at the end of 
+your resource parameter.
