 ## How to add an endpoint
 
+**Quick way**:
+
 Edit `mylibs/resources/mock.py` and add a rest class.
 The class should contain at least the get method.
 If you class is called `MyClass`, it will be reachable
-at the `api/myclass` address of the web server.
+at the `api/myclass` address of the web server.
+
+You can specify a different address overiding the attribute `endpoint` inside
+the class.
+
+**Cleaner way**:
+
+Define a file `confs/endpoints.ini` with the following syntax:
+
+```
+[module_name]
+class=endpoint
+```
+
+For example, after creating a file `myresource.py` inside `mylibs/resources`,
+containing two classes `One` and `Two`, you could use:
+
+```
+[myresource]
+One=foo
+Two=hello/world
+```
+
+The system would provide the two following working URLs:
+
+```
+# Resource One
+http://localhost:8081/api/foo
+# Resource Two
+http://localhost:8081/api/hello/world
+```
