Baby steps, first DF mission

[Seeker]

Mission files:

Probably a very obvious question, but which files, exactly, constitute a mission in this new format?

I'm on my laptop at the moment, but I've network access to my game machine's system drive, the user profiles are on a different volume. The game is a default steam install. Game machine is running Win7 U with UAC disabled so there's no virtual user file structure.

Am I cool doing a search for a text file called "death from above.mis" in program_files/bla/bla, or is there a properties file (is there one?) as well and of course I've tried making a simple briefing.

Maybe a sticky post with some FMB fundamentals (or a beginners guide link list) could be appropriate?
