 Named Servers
 =============
 
-By default users can run up to ``2`` simultaneous servers using the
-`named servers functionality in JupyterHub <https://jupyterhub.readthedocs.io/en/stable/reference/config-user-env.html#named-servers>`_.
+By default, users can run only one server at once.
 
-If a user tries to start more servers, they will be shown the following message:
+`Named servers functionality <https://jupyterhub.readthedocs.io/en/stable/reference/config-user-env.html#named-servers>`_ in JupyterHub

+To allow up to 2 simultaneous named servers (in addition to the default one), create the file ``named_servers_config.py``
+in the directory ``/opt/tljh/config/jupyterhub_config.d`` with the following content:
+
+.. code-block:: text
+
+   c.JupyterHub.allow_named_servers = True
+   c.JupyterHub.named_server_limit_per_user = 2
+
+Then, reload tljh:
+
+.. code-block:: text
+
+   sudo tljh-config reload
+
+Have a look to `named servers documentation <https://jupyterhub.readthedocs.io/en/stable/reference/config-user-env.html#named-servers>`_
+for more details.
