+## Hooks
+
+If you need to execute a script before or after each backup, 
+you need to add your hook script in the container folder `/hooks`:
+```
+-v ~/home/user/hooks:/hooks
+```
+Call your pre backup script `pre-backup.sh` and post backup script `post-backup.sh`
+
 Please don't hesitate to report any issue you find. **Thanks.**
