GitHub Essentials

Push your code

gh repo create my-project --public --push\n# or, with a repo already on GitHub:\n\ngit remote add origin https://github.com/you/my-project.git\ngit push -u origin main

The full cycle

git add .\ngit commit -m "…"\ngit pull origin main      # get teammates' work first\ngit push origin main

Pull vs fetch

git fetch origin   # download but don't merge\ngit pull origin main  # fetch + merge

Clone

git clone https://github.com/someone/project.git\ncd project

Tip: git pull before git push, always. It keeps your local history in sync and minimises conflicts.
