I think it would be good practice for people to add this base class in
their local repo and add it to `.git/info/exclude` so it won't be pushed.
The if guard in the board configs are ok to be pushed, they won't hurt
others. So you can definitely push your Mira board config!

I guess you figured it out already. But for completenesses sake:
name = "sbabic"
serverip = "your.server.ip"
(If your localhost is your labhost, that is ...)
