I don’t think it’s about tools as much as culture - whether it’s a readme, a wiki or a chat log that’s not full of talk about the weather and scones (no, really), people have to be suitably incentivised to work that way. Something that isn’t a customer-deliverable (they aren’t going to directly care if you don’t record the weird business process that led to you implementing feature X the way you did; they don’t have a comparison which tells them that if it was recorded, changes could’ve been quicker/cheaper/less risky) is at risk of being cut as soon as there’s a hint of time pressure to get something out the door.

It’s coincidental that doing things in less of a “let’s all get in a room and talk about it for 3 hours” way should make keeping remote workers in the loop easier too.
