Closes #3331

[talagluck]

I'm having the same issues as with the last PR. I've gone through the setup steps, but I get a 404 when I try and go to http://localhost:3000/gitbook.com/docs. I also have a bunch of failures of the e2e tests ( but all of the bun commands run).

This is on the latest pull of the branch used in this PR.

@talagluck - it should be http://localhost:3000**/url/**gitbook.com/docs

Maybe this needs to be more clear in the readme?

[talagluck]

Thanks for the update - looks good!
