Removing the following from a clean install of docusaurus v2 causes 404s:

        blog: {
          showReadingTime: true,
          // Please change this to your repo.
          editUrl:
            'https://github.com/facebook/docusaurus/edit/master/website/blog/',
        },

actually, I'm not sure what's causing 404s. but, it seems like routing is all sorts of messed up by default. I can't tell if I'm doing something wrong, but really all I've done is cloned the project and created a page to see this 404ing.

It seems like you can't access a doc page by its direct url if it's set as the homePageId

This actually was fixed yesterday in #2777; strange, I assumed that @yangshun already published a bug fix release 🤷‍♂️.

Fixed in v2.0.0-alpha.56.
