Links broken in documentation

All of the links to methods in the "Available Schedules" section 404.

Hello, can I work on this issue?

I think updating the links in the README.md file will also update the docs as Documenter.jl reads it directly for the home page.

The rule of thumb for working on an issue like this is that no permission is required :). A tested PR is more than enough.

Sorry for that, I will test and commit the PR.
