How do I create a Seafile Server? It's the free option, just for me. (Also I can't open the desktop app, it says "Seafile Client is already running"

So how do I create a server? I mean I’ve searched it up and can’t seem to understand how to do it.

Like I’m in the seafile costumer center:

What do I do now? To create a server and start syncing.

That looks like maybe it is where you can download the Pro version, but I’ve never used that, so can’t be sure. You can download the community edition here: Download - Seafile

And the instructions for deploying are in the admin manual here: Outline - Seafile Admin Manual
