## Description

In https://github.com/gorilla/pat#how-to-use we share a link for
documentation, which takes us to https://gorilla.github.io/. And when we
click on “Learn more” for gorilla/pat it takes us back to the GitHub
repo for gorilla/pat.
I think this repetition doesn’t make much sense when we are landing on
the same page again.

## Run verifications and test

- [x] `make verify` is passing
- [x] `make test` is passing
