What is Branching?
Branching is the way to work on different versions of a repository at one time
By default your repository has one branch named main which is considered to be the definitive branch. The branches are used to experiment and make edits before committing them to main.
Simply Put, You create a copy of the main add some change some changes and if the proposed changes are good, they will be added to the main.

4.Select the blue Create branch box or hit “Enter” on your keyboard.
What is a Commit?
According to Github,
On GitHub, saved changes are called commits. Each commit has an associated commit message, which is a description explaining why a particular change was made. Commit messages capture the history of your changes, so other contributors can understand what you’ve done and why.
How to Make and commit changes?

README.mdfile. - Click the pencil icon in the upper right corner of the file view to edit.

What is a Pull Request?
According to GitHub,
Pull Requests are the heart of collaboration on GitHub. When you open a pull request, you’re proposing your changes and requesting that someone review and pull in your contribution and merge them into their branch. Pull requests show diffs, or differences, of the content from both branches. The changes, additions, and subtractions are shown in green and red.
How to Merge a Pull Request?
- Click the green Merge pull request button to merge the changes into
main. - Click Confirm merge.
- Go ahead and delete the branch, since its changes have been incorporated, with the Delete branch button in the purple box.
Now you can
- Create an open source repository
- Start and manage a new branch
- Change a file and commit those changes to GitHub
- Open and merge a Pull Request
Happy Learning!!!
