I think the readme is included in the github.io page?

I think this is automatically generated from this README.md for everest.github.io. In the past, I have informed @krealyt of every change to the documentation.

Thanks, I have added the libcap package to the prerequisites page.

Regarding generated docs: A docs.rst is automatically found by the nightly documentation build and added to github.io. So, after merging this here, it will work.

(Alternatively, you can have an index.rst in a doc directory inside the module, which is then also automatically used for github.io documentation.)
