@okdas I reviewed the cheatsheet but not the walkthrough (haven't done the steps myself yet).

Can you please do the following:

1. Review m changes in the cheatsheet (validate, update, etc...)
2. Make the corresponding change sin the walkthrough

I'll do a round 2 later this week.

[okdas]

Thanks! Will add your changes to the walkthrough as well.

Just looked over what was done - this is good to go as is, I should've requested a re-review back in December.
