In the following window, log in with the account that you created on Onlime.dk.

You will now see a brief explanation of how to automatically back up folders. Read the slightly longer explanation here.

The installation now suggests backing up the Pictures, Desktop, and Documents folder automatically. You can later change this and add other folders for automatic backup.

You will now see a brief explanation of how synchronization takes place. Read more about the difference between automatic backup and synchronization.

You can now choose to enable or disable Onlime Sync. This can also be done later from Settings.

Once you have completed the installation, you can open Onlime and start using the service.
