+# Running with Docker
+
+The repo ships a multi-stage `Dockerfile` (Next.js standalone output,
+runs as a non-root user) and a `docker-compose.yml` with a single
+`app` service. Supabase is external — point the app at your hosted
+(or self-hosted) Supabase project via env vars; no database container
+is included.
+
+## Quick start
+
+1. Copy the env template and fill it in:
+
+   ```bash
+   cp .env.local.example .env.local
+   ```
+
+2. Build and start (the `--env-file` flag is required — Compose only
+   reads `.env` by default for `${VAR}` substitution, and this project
+   keeps its config in `.env.local`):
+
+   ```bash
+   docker compose --env-file .env.local up --build -d
+   ```
+
+3. The app is served on [http://localhost:3000](http://localhost:3000)
+   (override the host port with `PORT=8080` in `.env.local`).
+
+## Build-time vs runtime variables
+
+- `NEXT_PUBLIC_*` variables are **inlined into the client bundle at
+  build time**. They are passed as Docker build args by
+  `docker-compose.yml`. If you change any of them, rebuild:
+  `docker compose --env-file .env.local up --build -d`.
+- Everything else (`SUPABASE_SERVICE_ROLE_KEY`, `ENCRYPTION_KEY`,
+  `META_APP_SECRET`, …) is read at **runtime** from `.env.local` via
+  `env_file` and is never baked into the image — safe to change with
+  just a container restart.
+
+## Plain Docker (no Compose)
+
+```bash
+docker build \
+  --build-arg NEXT_PUBLIC_SUPABASE_URL=https://your-project.supabase.co \
+  --build-arg NEXT_PUBLIC_SUPABASE_ANON_KEY=your-anon-key \
+  -t wacrm .
+
+docker run -d --env-file .env.local -p 3000:3000 wacrm
+```
+
+## Notes
+
+- Database migrations under `supabase/` are **not** run by the
+  container — apply them with the Supabase CLI as described in the
+  README.
+- If you use automation Wait steps, remember to point your cron pinger
+  at `GET /api/automations/cron` on this deployment (see
+  `docs/automations-and-cron.md`).
