Description & motivation

Per @mirnawong1's feedback, the two details blocks are not showing up in the bottom of the page. I think they might just need to include a summary?

When I come back to this:

• Move content out of details tabs
• Can we reconfigure this content to make it easier to read?
• Add context requested from @pofl

I do want to make a small request here. The docs do not mention what type the updated_at field of the timestamp strategy should have. timestamp types work, of course. But what about ISO date strings and unix epoch integers? Please add this (one sentence) to the docs. You can even hijack this PR to add that.

@runleonarun : So sorry for the delay in getting this reviewed! As you might have heard, the Docs team will be dedicating time on a regular cadence to manage our PR backlog better. In the spirit of this, I opened this PR to see what I can do to help it along.

Your changes look good and ready for approval but I wasn't sure whether you were going to work on this PR further. Are you ready for me to review this or do you need to make more changes? Thanks!

Thanks for the nudge @nghi-ly! I moved the additional thoughts for improvement over to an issue so we can get this merged and fix the error. Can you please review it as is? Thank you! 🙇🏻‍♀️
