For future tutorials, I am going to be separating each step in a new branch, making it easy to follow.

The appearance of the readme would be something similar to the following:

Each step is a branch. Check out to the step you want to test.

$ git checkout <step-number>    # eg: git checkout step-1

• step-0 - Adding a first branch step-0.
• step-1 - Adding a new branch step-1, from scratch.

Everytime I can pull each branch to merge it with the main branch

• step-2 - Adding a new branch step-2, from the old step-1 branch.
• and so on..
