To contribute to the project, join the Discord server with this link. More details about our Discord server, its channels, rules, etc. can be found here. If you'd like to contribute to the wiki as well, first register here then send your username to Daeken on Discord and request write access.
We are limiting wiki write access as well as certain parts of the Discord server to those with reverse-engineering experience or specific skills. We want to allow everyone in, but we need to be able to keep certain details private to prevent bugs from being fixed too early, and things like that. Basically, if you know you want to help and have the skills (or at least the drive to get those skills) to do so, you probably won't have a problem getting in.
If you'd like to donate to the project, to fund tools and hardware, please talk to us in Discord #general or message Daeken directly.
