 The `simon987/sist2` image comes with common languages
 (hin, jpn, eng, fra, rus, spa) pre-installed.

+# Systemd integration example
+
+This example contains my (yatli) personal configuration for sist2 auto-updating.
+The following indices are involved in this configuration:
+
+| Index     | Path             | Description                                |
+|-----------|------------------|--------------------------------------------|
+| files     | /zpool/files     | Main file repository                       |
+| nextcloud | /zpool/nextcloud | Externally synchronized to a cloud account |
+
+The systemd integration achieves automatic sist2 scanning & indexing everyday at 3:00AM.
+
+### Tailoring the configuration for yourself
+
+`sist2-update-all.sh` calls update scripts for each sist2 index. Add or remove
+update scripts accordingly to suit your need. Each update script (e.g.
+`sist2-update-files.sh`) has important parameters laid down at the beginning so
+make sure to edit them to point to your files and index locations.
+
+### Installation
+
+```bash
+# install the services and scripts
+sudo make install
+# enable & start the timer
+sudo systemctl enable sist2-update.timer
+sudo systemctl start sist2-update.timer
+# verify that the timer has been enabled
+systemctl list-timers --all
+```
