Recommended method: follow the automatic upgrade procedure. If you're currently running Piwigo 2.1, the Automatic Upgrade will tell you which plugin may be not compatible with Piwigo 2.2 before upgrade.
If you're running Piwigo 2.2.x, you can also download the 2.2.x_to_2.2.5.zip archive that contains all new and modified files. Once you have extracted the files, transfer them onto your web server with a FTP client (like FileZilla) over your Piwigo 2.2.x installation. No database upgrade is required.
If you are running a version older than 2.2.0 and do not want to use the automatic upgrade, then follow the manual upgrade.
