By David Montigny on 2/21/2026

Instructor fumbles a lot through the steps and repeats himself and does not fully cover topics. Many of the steps could only be completed using external information. He provides full instruction for using Windows only and leaves out thorough instruction for Linus and groups it in with Mac instructions, many of which are outdated and incorrect for up to date systems. A lot of the Java Script instructions are incorrect.
