That text is unmodified from upstream's README.

It's a little unfortunate that GitHub provides so little room to add your own README to a fork, short of modifying upstream's README in the source code itself. You get a sentence at the top, which is about it.

I've seen people create their own README and move the upstream one to README.upstream or similar. Seemed sensible to me.

But unfortunately that change will then be included in all pull requests, unless you create a clean branch for every change you want to get into upstream.

GitHub should allow you to choose which file to use as the readme, just like they allow you to choose the default branch.

Or "README.forkname" or "README.user-forkname"...
