+About dashes
+------------
+
+Since Python doesn't allow dashes in method names, but Keycloak URLs use them in some places,
+Mantelo automatically converts any underscores in method names to dashes in the URL.
+
+In other words, to call:
+
+.. code-block:: none
+
+    GET /admin/realms/{realm}/client-scopes
+
+You can use:
+
+.. code-block:: python
+
+    c.client_scopes.get()
+
+Note that you could also use ``c("client-scopes").get()``, but let's admit it, it is ugly (so
+don't).
+
 Special case: working with realms
 ---------------------------------
 
-
 By default, a client is bound to a realm, and has the base URL set to
 ``<server-url>/admin/realms/<realm-name>``. Hence, to query ``GET /admin/realms/<realm-name>``, you
 can use :python:`c.get()` directly (or :python:`c.post({})` to update its properties).
