I am working on a large project, and have two computers I'll be using to do so. I created the initial project on my iMac, and want portability to work on it with my laptop.
So far I cloned the repo, using:
git clone https://github.com/YOUR-USERNAME/YOUR-REPOSITORY
git remote add origin remote repository URL
git push -u origin master
Updates were rejected because the tip of your current branch is behind
You need to merge the remote branch into your current branch by running git pull
