 ## Repository layout
 
-| Path | Purpose |
-|------|--------|
-| `conf/config.local.php` | ENV-driven PostfixAdmin config (baked into image). |
-| `Dockerfile` | Builds from `postfixadmin`, copies `conf/config.local.php`. |
-| `docker-compose.yml` | Sample stack: one service, env vars enumerated so the container receives them. |
-| `.env.example` | Documents all `PFA_*` variables (required vs optional, no secrets). |
-| `.woodpecker/ci.yml` | CI: install deps, Prettier format check, YAML lint. |
-| `.woodpecker/build.yml` | Build: Docker build (linux/amd64), push to registry. |
-| `.woodpecker/deploy.yml` | Deploy: trigger stack redeploy via webhook (no clone). |

 Secrets and deployment-specific values are not stored in the repo; they are supplied at deploy time (e.g. stack environment in your orchestration UI).
 
-## Configuration (PFA_* env vars)
+## Configuration (PFA\_\* env vars)
 
 - **Required (no default):** `PFA_SETUP_PASSWORD`, `PFA_DATABASE_PASSWORD`, `PFA_ADMIN_SMTP_PASSWORD`. The app will exit with a clear error if any of these are missing.
 - **Optional:** All other `PFA_*` variables have defaults in `config.local.php`. Override them via environment to match your site (database host, site URL, branding, SMTP, quotas, feature flags, etc.).
