Where to post gitHub-slideshow errata

I finally found the slideshow and am going through the tutorial but there are errors, misdirected links, and sections where it says one thing but it means something else.

Where can I create an issue and post corrections for the github-slideshow tutorial?

Is this the issue page where I should post them? GitHub - githubtraining/github-slideshow-demo: Demo repository for the Introduction to GitHub course

Example:
On page Getting Started with GitHub · Issue #1 · datatalking/github-slideshow · GitHub

It says :keyboard: Activity: Enable GitHub Pages

  1. works fine
  2. works fine
  3. From the “Source” drop down, select main branch

Solution:
There is no “Source” on the whole page, instead, it could read "From the left side of the [menu name] click “Pages” and under the “GitHub Pages” Source submenu click “None” drop down, select main branch
