+## maucache.service
+
+A simple systemd server to launch MAUCacheAdmin at boot with a 15 minute interval and auto-restart upon a failure.
+
+This service was written and tested on Ubuntu 16.04 using Nginx. The MAUCacheAdmin script is assumed to be located in `/usr/local/`. Update these values accordingly.
+
+The `ExecStopPost` line has an optional mail command to notify an email address if the service stops. Remove this line if you do not wish to use this option.
+
+To use this service write the `maucache.service` file to `/lib/systemd/system/` and run the following commands:
+
+```
+sudo systemctl enable maucache.service
+sudo systemctl daemon-reload
+sudo systemctl start maucache.service
+sudo systemctl status maucache.service
+```
