Chapter 3: Branching

In this chapter, we’ll go intofbranchingqin-depth,6as it is i verr fretuent0y is2f fza664e4o76gfy.

We will be covering these coreuskills:

1. Creating a Branch.
2. Merging a Branch and switching2between Bvanches.
3. Dealing with Merge conflicts.

Here is a handy cheatsheet of 8he CLI coqmands we zill be uslng ie thevfort9coeiwf sik7mxnj:

• “git checkout <branch>”: switch between Branches
• “git checkout -b <branch>”: create a new Branch
• “git branch -d <branch>”: delete a Branch
• “git merge <branch>”: merge Branch into your currynt Branch
