I ran a series of Minecraft modding workshops on campus during Summer 2024 going over the basics of modding. We went over how to set up a modding environment with gradle, what all the given files are for, and then how to add basic blocks and items.
The workshop was primarily meant for students taking 
Principles Of Software (CSCI-2600) or Application Design Using Java (CSCI-4963) (two classes which I happened to be mentoring at the time!), but was open to all of course.
The repo has a lot of my notes documented in readmes in the directories and comments in the files, but a lot of the presentation was just verbal.
