sorry i don't have enough time to thoroughly review this, i was hoping that @viren-nadkarni could maybe browse through it and give feedback on the content.

in terms of layout: it looks REALLY good. the navigation is super nice and the presentation looks wonderful.
just one minor nit: instead of having the button on the bottom of the lesson say "LEARN MORE" i would maybe call it "Next Lesson"

really great job everyone! 👏 @Nancy-Chauhan @webdev51 @tinyg210

Great stuff @Nancy-Chauhan!

Overall the content and recordings are excellent. I only have a few nitpicks/suggestions.

I strongly recommend using one sentence per line in all the markdown files.

Also, I felt the language was a bit too marketing heavy, with too many instances of words like 'revolutionary' or 'exciting' or 'game-changing'. We might want to tone it down it future iteration since this is intended to be educational in nature :)
