In order to code along with the course (starting with Chapter 1), should I only clone the "chapter 1" branch, not main?

🐞 Starting the course and trying to code along

I've just started this course and would like to write some code following the exercises. I've already set up Node.js, VS Code and terminal (Hyper as I have Windows, not iTerm).
I have forked the repo and cloned it to my laptop but I've cloned the main branch - which, I realize now, at Chapter 2, contains everything completed, all exercises already done (for example, in Chapter 2.3 I'm supposed to write my first test but it's already in the file).

Should I just delete the repo and start over, cloning only the "chapter 1" branch?

Thank you for your help!

A friend told me that I need to clone the whole repo and then, working locally, check out the chapter needed (starting with number 1) and work in that branch.
Please close this issue if this is correct.

@Tungstic How can I check out the chapter needed?
