I finished the course a few days ago and it was awesome. Of course it is not a fully functional complete clone, but it is an incredible learning resource.

It really starts from the beginning as in "first you have to install the proper tools and prepare your software development environment" beginning. Which is great to teach you things that you wouldnt learn in other free online courses.

I think it is a essential resource that present you the full stack of a web app, acting as the perfect complement to more pure code oriented courses like freecodecamp and codecademy.

And you can really start from zero coding knowledge. I fully recommend it.
