Open your Terminal or Command Prompt and navigate to the Repository containing the branch you would like to merge.

Type "git branch [[Enter]]" to display a list of all branches. You'll have to switch to the branch you want to merge into to successfully merge. To do this, enter the following commands:

Type "git add _a [[Enter]]" to add a branch to the staging area.

Type "git commit -m "commit message" [[Enter]]" To add the commit message.

Type "git checkout main [[Enter]]" To run a Git Checkout to switch to your main branch.

If the branch you would like to merge is behind your main branch, you'll need to do a fast-forward to catch up. To do this, Type "git pull [[Enter]]"

Now, you can merge your branch into the main branch. Simply type "git merge second-branch [[Enter]]"

In this tutorial, we'll merge a feature branch into your master branch. You might want to do this after working on a new feature or bug in your secondary branch. When the time comes to merge back into the rest of your project, follow these steps.
