At long last, I finally got the start of some documentation for NAM's trainer online. Have a look here:
You'll find the information about installing, tutorials using the Colab, GUI, and full-featured CLI trainer (all of which used to be in the README), and the start of the documentation on the package API.
This is a great way to started contributing to the project! If you've wanted to get involved but didn't know what to do, consider contributing to the documentation--any information I've missed, additional tutorials, filling out the documentation on the package (some of it is as simple as getting some of the classes and modules auto-generating correctly)--all of this is a great way to share knowledge, best practices, and little tips and tricks. It's also a great way to check your understanding if you're a little unsure about how things work before tackling a bug fix or new feature.
Enjoy!
