-## Railway Provisioning
+## Docker
 
-After `railway login` succeeds, provision and deploy the first-pass stack:
+Uploaded HTML is stored on the filesystem. Compose bind-mounts `./data/html` to `/data/html` in the app container so drafts persist across rebuilds. Override the host path with `POSTPLAN_HTML_VOLUME`.
 
 ```sh
-chmod +x scripts/provision-railway.sh
-scripts/provision-railway.sh
+docker compose up --build
 ```
 
-The script creates a Railway project, app service, Postgres service, object storage bucket, service variables, Railway domain, and first deployment. It stores the generated bootstrap API key under `~/.postplan/deployments/`.
-
-Verify the deployed service:
-
-```sh
-POSTPLAN_URL=https://your-railway-domain \
-POSTPLAN_API_KEY=your-bootstrap-or-cli-key \
-scripts/verify-deployment.sh
-```
+The API listens on `http://localhost:3000`. Point the CLI at it with `--api-url http://localhost:3000`. The default bootstrap key is `dev-bootstrap-key`; set `POSTPLAN_BOOTSTRAP_API_KEY` to override it.
 
 Create a named key from the bootstrap key:
 
 ```sh
-curl -X POST "$POSTPLAN_URL/api/api-keys" \
-  -H "Authorization: Bearer $POSTPLAN_BOOTSTRAP_API_KEY" \
+curl -X POST "http://localhost:3000/api/api-keys" \
