 Here is a awesome website with [some examples](https://crontab.guru/examples.html) and an [explorer](https://crontab.guru/)
 
+## Installing the cron
+
+To actually enable cron jobs you need something to call `autorestic cron` on a timed shedule. Note that the shedule has nothing to do with the `cron` attribute in each location. My advise would be to trigger the command every 5min, but if you have a cronjob that runs only once a week, it's probably enough to shedule it once a day.
+
+### Crontab
+
+Here is an example using crontab, but systemd would do too.
+
+First, open your crontab in edit mode
+
+```bash
+crontab -e
+```
+
+Then paste this at the bottom of the file and save it. Note that in this specific example the `.autorestic.yml` is located in `/srv/`. You need to modify that part of course to fit your config file.
+
+```bash
+0 * * * * /usr/local/bin/autorestic -c /srv/.autorestic.yml
+```
+
+Now you can add as many `cron` attributes as you wish ⏱
