+    Archive:  pocketbase.zip
+      inflating: /home/isabell/bin/pocketbase
+    [isabell@stardust ~]$
+
+It should be added to your path automatically. Now test if it works:
+
+.. code-block:: console
+
+    [isabell@stardust ~]$ pocketbase -v
+    pocketbase version 0.22.8
+    [isabell@stardust ~]$
+
+
+Setup Supervisord
+=================
+
+First create a folder where all data is stored:
+
+.. code-block:: console
+
+    [isabell@stardus ~]$ mkdir ~/pocketbase
+    [isabell@stardus ~]$
+
+
+.. warning::
+    To modify this specific running instance of Pocketbase (e.g. updating, user management),
+    all ``pocketbase`` commands must be executed in the folder you just created!
+
+
+Now, create a configuration file ``~/etc/services.d/pocketbase.ini``:
+
+.. code-block:: ini
+
+    [program:pocketbase]
+    directory=%(ENV_HOME)s/pocketbase
+    command=pocketbase serve --http :8090
+    autostart=yes
+    autorestart=yes
+    startsecs=60
+
+.. include:: includes/supervisord.rst
+
+.. note::
+    Pocketbase is running on port 8090.
+
+.. include:: includes/web-backend.rst
+
+
+Creating an admin user
+======================
+
+First, find out your domain name:
+
+.. include:: includes/web-domain-list.rst
+
+To create an admin user open ``https://isabel.uber.space/_/`` (mind the underscore in the URL) and follow through the
+instructions of the installer. Alternatively you can use the admin CLI via ``pocketbase admin`` to create, delete and
+update admin users.
+
+
+Updates
+=======
+
+.. note:: Check the update documentation_ or releases_ page regularly to stay informed about the newest version.
+
+To update the current executable you have two choices:
+
+* Repeat the steps in the *Installation* section above.
+* Run the built-in updater using ``pocketbase update`` inside ``~/pocketbase``
+
+After updating, tell :manual:`supervisord <daemons-supervisord>` to restart the service:
+
+.. code-block:: console
+
+    [isabell@stardust ~]$ supervisorctl restart pocketbase
+    SERVICE: stopped
+    SERVICE: started
+    [isabell@stardust ~]$ supervisorctl status
+    SERVICE                            RUNNING   pid 26020, uptime 0:03:14
+    [isabell@stardust ~]$
+
+
+Breaking changes
+----------------
+
+Pocketbase is still in early development. Hence, a new realease might introduce breaking changes.
+While updating you might need to run a migration using ``pocketbase migrate``. Please refer to the documentation_.
