One primary concern - the intent here is for the new website, not fast-frame concept :)

have approvals

I spoke with Jeff and we agree to put this in its own folder to reduce the risk of issues and concerns I had that would increase PR review times.

Also, I updated all branch policies to remove Circle CI and use GH Actions. If there are adjustments you'd like made to features/* let me know.

@chrisdholt This is actually what I've been working on in bits and pieces. I have a full setup for the new site already. The only piece I'm missing is the reference documentation, which I was hoping to finish tomorrow. It's all Docusaurus v2 based. There's just a placeholder for the new home page that needs to be filled in once we're ready to build that.

Just synced with @chrisdholt to confirm that @eljefe223 and company should continue on this work and I'll continue on mine. We'll bring the two together when they are ready. It should be pretty easy to drop a custom home page into the Docusaurus setup I'm working on, which will give us a nice unification of the marketing piece with the docs.
