If you want to see what output looks like (for smaller projects--the OP shared some for other, more popular projects), I posted a few of the tutorials to my GitHub:

https://github.com/mooreds/prime-mvc-tutorial

https://github.com/mooreds/railsquickstart-tutorial

https://github.com/mooreds/fusionauth-jwt-tutorial/

Other than renaming the index.md file to README.md and modifying it slightly, I made no changes.

Edit: added note that there are examples in the original link.
