+Loki
+====
+
+Docker files for my server, Loki.
+
+Installation
+------------
+
+The following command will install the service file, reload systemd, and enable
+the service
+
+::
+
+   make install
+
+Uninstall with
+
+::
+
+   make uninstall
+
+Usage
+-----
+
+To start the service run
+
+::
+
+   service loki-server start
+
+To stop run
+
+::
+
+   service loki-server stop
+
+To restart
+
+::
+
+   service loki-server restart
+
+Note that ``docker-compose`` might have issues with HTTP timeout so you may
+have to increase the ``COMPOSE_HTTP_TIMEOUT`` environment variable. ``300``
+should be enough.
+
+Updating
+--------
+
+To update the images and restart run (``WARNING: THIS WILL REMOVE ALL UNUSED
+DOCKER IMAGES``)
+
+::
+
+   ./update.sh
