best way to keep an NoCMS-environment up to date ?

[kal60]

Hi!
First of all: thanks for creating this great "piece" of software. I started a year ago to develop with CI and switched over to NoCMS last year - this make all a lot easier to implement the appilactions. I'm just migrating apps from CI-MVC to NoCMS (with HMVC). I've got a dev- and a prod-environment of NoCMS. What will be the best method to:
a) keep the dev-env up to date ? (e.g. by getting the latest from your github-repository via git ? How to keep a local git repo parallel to save the own changes, e.g. in own modules ?)
b) to migrate the dev to prod-environment ?
Could you please give some suggestions ?
Thanks in advance
