I'd like to document the CLI and have come to the conclusion we could mimick the style of a 40 page vyatta pdf docs per article about a subject or create per cli option an page with it's documentation + some index pages to steer people in-the-good-direction(tm).

I'd like to do the latter with the idea it could be cool to implement it on vyos as a periodical fetch to update local docs with usage 'explain set interfaces ethernet eth0 address 4.2.2.1/24'.

Eitherway, what's prefered: long articles or cli-option-based articles with indexes as glue?
