GitHub help needed: How can I get a new branch from the main repo to my own fork?

Development

Nick gave me the following instructions when I mentioned not being able to keep my Fedora box in sync with with the 5.2 revisions.

I was hoping to work it into a less frightening wiki document than our current set. One that makes it easier for non-developer users to move up to beta (or alpha) tester. Or for experienced developers to explore with less onboarding investment. And where the simple instructions work on all 3 primary platforms. Unfortunately, my understanding is too shallow to write a proper page.

In the terminal, clone the repository with:
git clone https://github.com/gramps-project/gramps.git Gramps

Change directory:
cd Gramps

Create a tracking branch:
git checkout -b gramps52 origin/maintenance/gramps52

When you want to pull in the latest changes use:
git pull

and earlier eMail advised the following after refreshing

Change directory to the local instance of the Gramps beta:
git clean -dfx
python3 setup.py build
python3 Gramps.py
