Some links broken in README.md

There are some broken links in the README.md file.

I noticed them when looking at the section for generating usage documentation from templates

The linked files no longer exist.

I didn't scour for other possible stale links.

I, too, was looking for the docs on how to generate documentation and ran into this issue. Not sure if/how to generate documentation now, which would be great to have for my project.
