Hi @catherinep, welcome to the Vercel Community!

1. We've this How to Deploy a Docusaurus Site with Vercel guide in our knowledge base that will be helpful.
2. If your marketing side is hosted on Vercel, you can use the rewrites configuration in your vercel.json file to achieve this.
3. You can use Vercel preview deployments without any additional set up. It should work automatically for PRs.

Thanks for the guidance and the link — this helps.

One clarification on our setup: our main marketing site is not hosted on Vercel. We are planning to host only the documentation on Vercel.

We’ve already created a local Docusaurus setup and will likely push it to GitHub as the next step before importing it into Vercel.

Since we need to retain the existing example.com/docs/ path, our understanding is that this would be handled via our existing reverse proxy, routing /docs/* → the Vercel Docusaurus deployment

Please suggest.
