Backup you saves in case something goes wrong
Download Rclone
Setup a cloud service of your choice using a guide on Rclone's site, the only requirement is to name the drive "satisfactory".
Open the .bat file and replace `[ID]` with your store's ID. There's a random [guide](https://www.ubisoft.com/en-gb/help/account/article/finding-your-steam-id/000060565).
Disabling of cloud saves in your store's launcher is recommended to avoid mixing of your and your friend's saves.
All your friends have to setup Rclone with the same cloud account.
Now you're all prepared. From now on, if you want to play a single player game start the game normally. If you want to play a synced multiplayer game, start the game using the .bat file.
