Merging class repo file for real this time

Adding my github repo link

[crsl4]

@jlemaire104 there is a section in the file that got lost (at the very top):

---
layout: default
nav_exclude: true

Can you add it? You simply need to modify your own file, do the git add, git commit and git push, and the pull request will be automatically updated.
