 An experimental borg implementation for yunohost
 
 ## Usage
+If you want to backup your server A onto the server B.
+
+## Setup borg app on Server A
+Firstly set up this app on the server A you want to backup:
+
+```
+yunohost app install https://github.com/YunoHost-Apps/borg_ynh
+Indicate the server where you want put your backups: serverB.local
+Indicate the ssh user to use to connect on this server: servera
+Indicate a strong passphrase, that you will keep preciously if you want to be able to use your backups: N0tAW3akp4ssw0rdYoloMacN!guets
+Would you like to backup your YunoHost configuration ? [0 | 1] (default: 1):
+Would you like to backup mails and user home directory ? [0 | 1] (default: 1):
+Which apps would you backup (list separated by comma or 'all') ? (default: all):
+Indicate the backup frequency (see systemd OnCalendar format) (default: Daily):
+```
+
+You can schedule your backup by choosing an other frequency. Some example:
+
+Monthly : 
+Weekly : 
+Daily : Daily at midnight
+Hourly : Hourly o Clock
+Sat *-*-1..7 18:00:00 : The first saturday of every month at 18:00
+4:00 : Every day at 4 AM
+5,17:00 : Every day at 5 AM and at 5 PM
+
+See here for more info : https://wiki.archlinux.org/index.php/Systemd/Timers#Realtime_timer
+
+At the end of the installation, the app display you the public_key and the user to give to the person who has access to the server B.
+```
+You should now install the "Borg Server" app on serverb.local and fill questions like this:
+User: servera
+Public key: ssh-ed25519 AAAA[...] root@servera.local
+
+If you don't find the mail and you don't see the message in the log bar you can found the public_key with this command:
+```
+cat /root/.ssh/id_borg_ed25519.pub
+```
+
+## Setup Borg Server app on Server B
+
+```
+yunohost app install https://github.com/YunoHost-Apps/borgserver_ynh
+Indicate the ssh user to create: servera
+Indicate the public key given by borg_ynh app: ssh-ed25519 AAAA[...] root@servera.local
+```
+
+## Test
+At this step your backup should schedule.
+
+If you want to be sure, you can test it by running on server A:
+```
+service borg start
+```
+
+Next you can check, your backup on server B
+```
+borg list /home/servera/backup
+```
+
+YOU SHOULD CHECK REGULARLY THAT YOUR BACKUP ARE STILL WORKING.
