Revamp Wiki Documentation

[robotgoat]

Hello, I've been an avid follower of the iNav project and primarily have used Youtube sources from the likes of Paweł Spychalski, painless360, Joshua Bardwell, and others to learn about and configure an quadcopter with iNav.

In comparison to the iNav wiki, I found the guides to be a little hard to find exact information quickly and would like to help contribute by reorganizing the offiical wiki into a MkDocs format. Would this be a reasonable contribution I could make?

Thanks!
