 This is Guix system (container) configuration used for the system serving
 https://koszko.org
 
+# Use & installation
+
+The command
+
+```shell
+make && sudo make start-container
+```
+
+causes the container to be run in a test enviroment, with some host directories
+(e.g. `/var/www/koszko.org/html`) faked to contain sample files.
+The command
+
+```shell
+make fake-client
+```
+
+spawns a shell in which `koszko.org` and some other domains resolve to the IP
+address under which the container services are visible to the host.
+The command
+
+```shell
+make enter-container
+```
+
+spawns a shell inside the previously-started container. Finally,
+
+```shell
+sudo make install
+```
+
+registers the container startup script as a Guix gc root and creates an
+`/etc/init.d` SysV-style init script for starting it.
+The container can then be started by systemd with
+
+```shell
+sudo systemctl daemon-reload # only needed once after installation
+sudo systemctl start guix-container
+```
+
+or by the good old SysV init with
+
+```shell
+suso service guix-container start
+```
+
+You can of course also use other systemd or SysV init commands to manage the
+container service.
+
+Feel free to look into the `Makefile` to see what other helpful targets are
+available.
