Runbooks

A service runbook is a concise, structured document that outlines the standard operating procedures for running, troubleshooting, and maintaining various services.

Its purpose is to give engineers (especially on-call or incident responders) the exact steps needed to quickly understand the service, handle common problems, and recover from failures — without having to dig through large amounts of documentation.
