You can help other people with their problems if you know enough about the most common problems people have (except for those in the FAQ, which you can of course redirect them to). Otherwise, you can translate if you know English and another language, use a torrent client (I recommend qBittorent) to seed the „Nexus 2“ client (this is a big help to me since I am paying the file hosting costs out of pocket), or tell others about the project and encourage them to join.
