my docs are a single page full of one liners for practical issues that have organically arisen several times over the years, with a table of contents at the front.

As I said, I write good docs, but no-one will read them until they have been caught out 3 times asking obvious questions had they gone to the doc first. If I am not around, I know the docs will be abandoned immediately despite it representing a tome of hard won knowledge that saves an incredible amount of aggregate time from never needing to figure out how to do the same task twice.
