Confusion on how to launch Automodel examples, especially on multi-node

Is your feature request related to a problem? Please describe.
There should be a quick-start/recipe for launching SFT/PEFT for Nemotron Nano v3 using Automodel. Users going directly to Nemotron v3 example configs found an old usage example that pointed to a different config and had incorrect commands. No information on how to run on multi-node.

Describe the solution you'd like
Create a self-contained full guide for fine-tuning Nemotron Nano v3 using Automodel that includes: which container to use, how to launch it on different platforms (Slurm, standalone Docker, etc), where Automodel exists inside the container, how to launch the training run, and how to modify for multi-GPU/multi-node.
