Looking through the introduction, it doesn't say much in regards to what's allowed and what isn't. Can I work together with someone else? How much am I allowed to prepare beforehand?

I didn't really want to clutter the page with any more info, but basically, this is a permissive jam where whatever you want to do is probably ok.

I'm not sure I'd recommend forming teams, since that's likely to complicate the process of learning the tool - that's maybe a better idea in more compo like jams like Ludum Dare. But if you want to, that's fine.

You can do some reading and poking beforehand, sure. There will be a pretty wide range of experience levels coming to the jam, so I wouldn't worry too much about it. Nobody's going to disqualify you.

I've set the time to range all the way from Friday to Monday as well, so people can kind of "pick" their weekend. Yeah. It's very loose!
