Updating outdated installed GitHub Engine

I am not sure if this is specifically a VR question though I am only using the dev-ve-engine. So I figured to ask this here since I am using the VR version.
Scenario:
I have cloned the dev-vr-editor version from GitHub and after getting the dev version up and running it updates or someone improves upon the one that I have clonned… How do you update this? likw, do you have to re-download the engine and dependencies each time and build the solution file?
Or
Can you just run setup and rebuild the solution and that will update the version of the engine? Also using Visual Studio 2017 won’t make a difference will it?

Thanks for clearing this up for me in advance! I have been curious about this!
