"Also, keep in mind that documentation is very much a work-in-progress! The techdoc as it is is basically the state of the art with regards to what we’ve finished writing, editing etc. There’s still way more coming up, and the basic idea is to document everything very well this time; apart from some sensitive stuff (mostly the WiFi and BT RF interface) we’re trying to not have any secrets."
