The user-facing documentation lives at https://docs.healthlog.dev — that's the canonical surface for self-hosting guides, integration walkthroughs, AI-provider setup, and the doctor-report workflow.

The files in this directory are the internal operator playbooks, audit notes, and machine-readable specs that ship alongside the source:

api/ — the OpenAPI 3.1 spec for the native-client subset (iOS DTO codegen target). See api/README.md for the preview commands. Also home to the MCP-server contract: api/mcp-capabilities.md (tools, resources, prompts, write model) and api/mcp-skills.md (building a connector / skill).
ops/ — operator runbooks: deploy, backup / restore, encryption-key rotation, password reset and account recovery, env checks, TLS pinning, data repair. These are what an operator reaches for during an incident.
self-hosting/ — horizontal-scaling notes (HEALTHLOG_PROCESS_TYPE=web|worker|all) and the deploy-pipeline recipe. Routine install steps stay on docs.healthlog.dev. Includes self-hosting/mcp.md — enabling the off-by-default MCP connector and pointing Claude.ai / ChatGPT / Claude Desktop at it, and self-hosting/sso.md — OIDC SSO login: IdP setup, the identity-pinning security model, OIDC_ONLY consequences, and the break-glass runbook. Also self-hosting/geolite2.md — bringing your own offline GeoLite2 databases via GEOLITE2_DIR instead of sending login IPs to a third-party lookup. And self-hosting/account-sharing.md — letting one account on the instance open another's health record: the three access levels, the eight sections a grant can be narrowed to, managed profiles for somebody with no login and the guardians who look after them, what revocation does and does not undo, and which trust properties of the instance are unchanged by any of it. And self-hosting/support.md — reporting a problem: error ids, the support info every account can copy, the operator's redacted support report, and finding an error in the admin log.
using/ — notes on using the app that sit close to the code. using/search.md covers the command palette's record search: opening it, what it finds, how matching works, and its limits on very large and shared records.
migration/ — migration notes. Currently only v1.3 to v1.4; later releases are covered by CHANGELOG.md and https://docs.healthlog.dev.
integrations/ — per-integration reference (Withings, Fitbit, Google Health, WHOOP, Apple Health, AI providers, data import).
adr/ — architecture decision records.
security/ — threat-model notes.
diagrams/ — architecture diagrams rendered through docs.healthlog.dev.
releases/ — release imagery.
apple-store-connect-checklist.md — the iOS submission gate.
codex-protocol-spec.md — Codex / ChatGPT OAuth protocol reverse-engineering notes.
ui-guidelines.md — UI / a11y house style.
