First How-To Guides for the Manual

• Implementing a new Satellite in C++
• Porting a EUDAQ Producer

I thought writing some how-to guides is a good exercise to try out this documentation format, but also to find flaws or unanswered questions in our implementation. Neither of the above are fully finished but there are already some clarifications necessary:

• Do we want to be able to terminate satellites remotely, i.e. via CSCP? Then we should add a terminate command (or exit?) The corresponding transition (out of INIT, SAFE, ERROR, all others require stop and land first) should already be there, no?
• How exactly will the reconfiguration payload look like and work? Will the user code have to ensure all keys are used?
