CLI Catalog

[vmiller987]

Hello!

I made this CLI Catalog when I first started using nnUNet. I've found it to be a handy reference material. I generated this by examining the entry point files.

I believe this would be beneficial to any new users as it would give a simple location to examine all of the CLI arguments. For example, I shared the prediction section with another user (#2817 ) to answer his question.

If there's anything I need to fix, correct, or adjust, please let me know.
