go to plugins and install syncthing
once installed shut it down
enter the shell

created the user and use the UID you got from the last step
create the dataset and change the mounts permission to sync
connect a mount point to syncthing
start it back up and hit the manage button
create a username and password for the GUI
connect two devices and share a folder
