OP here - my hope is other software engineers/devs can use this as a tool to get knowledge out of their heads and into the hands of kids. Took a few days off during winter break and made/went through this with my kids.

Feedback/PRs appreciated.

Looks great and I have similar aged children who I shall try it on. Thank you

Thanks and you are very welcome! LMK how it goes / how I can improve.
