Documentation for Multiple Repositories

I want to automatically generate a documentation site that contains the ReadMe’s from all the repositories within my project. I am a little new to GitHub, so I’m not sure if my terminology is correct. I provide the link to the GitHub page that has all of the repositories.

https://github.com/casework

I was wondering if there is any way to have a website that automatically generates documentation for all the ReadMe’s found in any of the repositories. Ideally, this would be a website that recognizes if the ReadMe’s were edited or if a new repository was made, and then automatically update the documentation for the website. I have been looking at mkdocs and Sphinx, but I was wondering if there was an easy way to automatically generate and update documentation based on the ReadMe’s from these repositories. 

You may need to use the Github API to query your repositories, checking the status of Readme.md and fetching if new. Unless of course there’s a tool that’ll do that for you.
