When you are ready for a technical review/merge, post the for the link for the PR in the US-RSE Slack (#website) to ask for reviewers.

I don't know if this should go under the "Work Products" header or if "Code Review Resources" should also be a level 1 header.

Thanks for starting this @Aariq . After looking at this, and thinking a bit more, I wonder if listing all the resources on the website directly this way is the best path forward. I think it will be great having the resources as visible as possible, but I'm a bit concerned that this will make it hard to update in the future when we find more resources.

Could it make sense to create a curated document or spreadsheet that we "publish" and link to, or maybe better, embed on the page here?

What do others think?
