So basically this is a pretty "nooby" question but how would I get the latest version of my code from a GitHub repo? In my case, I code on both PC and Mac but I'd like to work on a project on both machines. For example, say if I started a project on PC, coded something and pushed it onto GitHub, then cloned that GitHub repo onto my Mac and coded some more and pushed that code to Github. How would I now update the code on my PC to match the code in the GitHub repo and vice-versa? Thank You!
