Pull Requests

Imagine a central (remote) GitHub repo with a team contributing code to it. Each one commits their work locally and pushes it directly to the GitHub repo's main branch. If it sounds like an easy way to have a broken mess of a codebase, it's because it is!

This is why developers merge branches on GitHub through pull requests.

On GitHub, a pull request is a way to propose changes, typically to the rest of your team, or to the maintainer of a project you're contributing to.

Pull requests allow team members to see what changes are being proposed and to discuss them before they are merged into the main codebase.

Assignment

Switch to a new branch called add_classics off of main.
Add another line to the classics.csv file:

Psycho, Alfred Hitchcock, 1960

Stage and commit the change, and prefix the commit message with L:.
Push the add_classics branch to GitHub with git push origin add_classics. If it doesn't exist on GitHub yet, this creates it.
Navigate to the GitHub repo in your browser
Click on the "Pull requests" tab near the top

Click "New pull request".

Set the base branch to main and the compare branch to add_classics, as we plan to merge add_classics into main later.

Create the pull request, but don't merge it yet!

Paste the URL of your GitHub repo in the text box and submit the checks.
