Workflow to work on atom core



I trying to hack some code on atom core. But I do not find an efficient workflow to do so. I have cloned and build atom on Windows. But script/build is very slow (some minutes). Hacking a src/*.coffee file, running script/build, check, coding, script/build, check is a very slow process because of script/build.

Is it possible to run atom from its repository (I mean running electron on the atom source repository)?
How main atom developer work on the project?
