You're hitting on the biggest problem with dev docs: they're always scattered because well they just want to jump straight back into coding.

For what you're describing, a place for onboarding, docs, and connecting to dev tools like GitHub, Superthread is a good fit. The layout is a lot more opinionated than Notion to reduce clunky navigation or UI.

It’s a place where docs and tasks are connected, so you're not jumping between a wiki and a task tracker. Specifically for devs it also has sprint functionality.
