This document exists to provide a template for documenting operational information about a service. The goal is to cover all of the bases so a reader can get a general understanding of the service and how to operate it.
The topics listed are a minimal starting point for documenting a service. Some won't be relevant, if so state why. Almost certainly some issues have been missed should be added to the template as they're discovered(<3 PRs).
