Notes for each Lesson, Request to the Maintainers

[dankgarlic1]

I am currently in Lesson 7, and even with adding comments it's really hard to retain moving forward, If you can provide some notes for each lesson which goes in intricate detail for example how to add and deploy the mockContract(Aggregatorv3) it would help a lot, this can fast pace our journey and we can always refer back to such documents, Thank you so much, rest I am really enjoying the course :)
