[chirp_devel] Old Newbie question

[Paul L. Schmidt]

Chirp Development Gurus,

I haven't done any formal software development/maintenance for years
(I'm retired), and am only vaguely familiar with git (I can download
code with it).  Yeah, I'm from the dark ages of RCS, CVS, SVN, etc. 

I've got code to add the Retevis RT20 to the existing radtel_rt18.py
driver.  There's an existing (5 year old) request to add the RT20 in
the system (#6067).  I added to the existing request to indicate I've
got working code, and uploaded a .diff file (yeah, nobody does that any
more, but I didn't want the work to get lost...).

Is there a brief tutorial on how to submit a proposed change with git?

(Yeah, when I was working on my RT-21V, I sent the changes to Jim,
KC9HI, who was kind/patient enough to add it... but I'd like to move
into the 21st century and learn how to do it right.)

73,
Paul, K9PS -- Yeah, I'm an old timer. That's not even a vanity call :-)
