+This app has gone through a major revamp!
+
+If you have multiple instances of this app, one upgrade will break all instances. You need to
+upgrade all apps. This is the last time it happens.
+
+Also, developer aren't flawless and we might have missed something during our tests.
+Please, PLEASE, check in a few days that backups are being done properly.
+
+If you want to manually check backups, run this:
+
+```bash
+systemctl start borg
+```
+
+Or, for a single app, for example Nextcloud:
+
+```bash
+sudo yunohost backup create --apps nextcloud --methods borg_app
+```
+
+If you find *any* issue or have a doubt, feel free to contact the devs on Github or Matrix.
+
+Backups are important. In any case, check your backups regularly.
