There was a problem hiding this comment.
Completed the tech pubs review of docs/design-docs/training-backends.md and provided some copyedits for grammar and punctuation. Also revised the Configuration heading levels to fix "stacked" headings (placing one heading directly beneath another without any intervening body text.) It tends to break the flow.

when running multinode, unless someone knows to mount
/opt/checkpointseverywhere, their multinode will fail. This change introduces the following dir precedenceMost will specify HF_HOME, so this will seemlessly work with those training large models on multiple nodes.
Also, default to the cache dir otherwise since
/optis usually reserved for "optional packages" as opposed to data mounts (which usually reside in/mnt)
