Platform Handbook

The single place for platform documentation: how the platform is planned, built, and operated, and how to add an application to it.

Application-specific documentation lives with the application (for example, the TodoList app keeps its local-development and chart docs in its own repository).

Status

This handbook is delivered like any other application: built in CI, pushed by digest, and reconciled by Argo CD. The platform itself is a work in progress — the design and its open questions are in Decisions, and the roadmap is tracked in the GITOPS-HUB, PLATFORM-RENAME, and OBSERVABILITY tasks.
