The new section includes:

How to switch to an existing branch
How to create a new branch and switch to it
How to check which branch you're currently on

Here's a brief overview of the changes:

• Switching Branches

• To switch to an existing branch, use the git checkout command. This command needs the name of the branch you want to switch to.

• Here's an example:

git checkout feature_branch

• If you get an error saying "pathspec 'feature_branch' did not match any file(s) known to git", make sure you've typed the branch name correctly.

• Creating and Switching to a New Branch

• If you want to create a new branch and immediately switch to it, you can use the git checkout -b command. This command needs the name of the new branch.

• Here's an example:

  git checkout -b new_feature_branch

• This command will create a new branch called new_feature_branch and switch to it. If a branch with the same name already exists, you'll get an error saying "A branch named 'new_feature_branch' already exists".

• Checking Which Branch You're On

• To see which branch you're currently on, you can use the git branch command. The branch you're currently on will be marked with an asterisk (*).

• Here's an example:

git branch

• This command will list all the branches in your repository. The current branch will be marked with an asterisk (*).Source

@smngvlkz Thanks so much for opening a PR! I'll get this triaged for review ✨

Hi @smngvlkz, and thanks for taking the time to write this PR up. Unfortunately, we won't be accepting this contribution; I've outlined our reasoning below.

In this case, most of the content isn't specifically relevant to the article's subject "Managing remote repositories", and could apply more generally. We also need to be careful to strike the right balance and not overload new users (whom these articles target) with content about Git and GitHub respectively.

For situations like this (improvement suggestions, rather than bug fixes) we'd really encourage you to open an issue in this repository first, so we can discuss the best ways to move things forward, before going ahead and creating content.

Thanks again for your time, and we hope to see you with more contributions in future. You can always review those issues with approved help wanted labels under https://github.com/github/docs/issues
