Proposal: Handle readme.md and README.md Equally for Cross-Platform Consistency

[fxi]

When publishing to GitHub via an action, the readme.md was not rendered as index.html, but as readme.html. It worked fine locally. It took me a while to understand that pkgdown is case-sensitive (as it should be), but macOS and Windows users, by default, use a case-insensitive file system. This can cause some confusion, especially for files where both case notations are accepted, like readme.md and README.md.

I think pkgdown should take this into account.

This feels like a risky precedent to me, because if we allow this for README.md then people will expect it for _pkgdown.yml and lots of other files. It's a bummer that it caused you some confusion, but I don't think modifying the package is going to decrease net confusion. Even though I'm closing this issue, I really appreciate the feedback, and hope you'll continue to contribute in the future 😄

Absolutely. I just realized this might be the first time I ever used a lowercase readme.md or encounter similar issue. Temporary lapse of clarity on my part. Appreciate all the hard work you put into maintaining half the R ecosystem 👍
