We just use the company wiki. We are thinking of moving that data to the service GitHub repo instead to keep the data more local. It is easy to forget to update documentation all ready, might as well reduce the places you have to update. Ideally all alerts are either self-evident or link to proper remediation steps to attempt when auto-remediation is not available. The new person on the team should have enough info to do basic triage at 3am at the very least given a decent runbook/alert documentation.
