Debug example demo - HTML Course

Hi guys, I am new to coding and still getting to grips with the basics. I am currently on the ‘HTML on MDN Web Docs: Debugging’ exercise of the HTML course, I have been told to read an article link: Debugging HTML - Learn web development | MDN (

In this article, I have been told to download the debug example demo, save it locally and open it in the browser.

I downloaded it using the code dropdown in github however I cant seem to open the folder in browser as I don’t have the knowledge to do so, could anyone help me with this?
