I can speak from experience. I did join once to a team, that was really some levels above me. BUT basically the only thing that helps is to actually work on something. Just ask the team for work. Of course the best would be for you to do something together with a senior. If there is someone who likes to help, this is your guy. In my case I think they thought, that this would only slow them down and there wasn't a "nice helper" guy there. So I did my best. It wasn't really good, BUT it was something that could be worked on. After that a lot of help came from the team, because it was kind of useful and later a central component.
