[DRAFT] Walkthrough

[f-dangel]

I wrote a rough scaffold with instructions that a reader should be able to execute.
Please try building the docs locally (mkdocs serve), then navigate to the 'Walkthrough Example' section and try running the commands.

I am sure there will be bugs. Let's start a list:

• FIXED: Always return tuple in load_latest_checkpoint
• BUG: At the moment, a SLURM job does not shut down after finishing a run, but instead requeues itself. I believe this must be related to some refactoring in the launch.sh script.

---

Additional TODOs:

• Complete content of the walkthrough (some text and screenshots missing)
• One polishing pass

Great, will check it out!

I think we have the bugs fixed now, so it would be good to merge this in soon.

I'd like it if the references to methods, e.g. checkpointer.step were linked rather than plain code, but I don't know how to set that up in mkdocs.
