Move PROCESS.md under the doc directory
PROCESS.md
includes some valuable info on how we work, but this info is neither on the docs site nor in the handbook. @winh approached me and thought about including it in the docs site, which I think is a good idea. he wrote to me:
I have had it happen a few times already that people searched information that was only in
PROCESS.md
but couldn’t find it in docs or handbook
Since this file resides in the root dir of the repo, it's not built like the other docs. To do this, we must do some magic in the rakefile that's used to build the site, but then again, we loose the ability to easily link to it from other places (as it's not relative to the other docs).
Maybe it's time we moved PROCESS.md
under doc/development/process.md
?
