-If you have installed Jirafeau using git, it's pretty simple: just make a git pull and chown/chmod files who have the owner changed.
-
-If you have installed Jirafeau just by uploading files on your server, you can take the [last version](https://gitlab.com/mojo42/Jirafeau/repository/archive.zip), overwrite files and chown/chmod files if needed.
-
-After upgrading, you can compare your ```lib/config.local.php``` and ```lib/config.original.php``` to see if new configuration items are available.
-
-If you have some troubles:
-- It should probably come from your ```lib/config.local.php``` (configuration syntax may have changed). Just compare it with ```lib/config.original.php```
-- Check owner/permissions of your files.
-
-Anyway you should off-course make a backup of your current installation before doing anything. :)
