+## Run with Docker Compose
+
+A quick single-node stack (app + Elasticsearch + Qdrant) is included:
+
+```bash
+docker compose build
+docker compose up
+```
+
+Services:
+- **app** (port 8080): Flask UI/API, embeds queries on demand (downloads the model on first run).
+- **elasticsearch** (port 9200): single node, security disabled for local use.
+- **qdrant** (port 6333): vector index used by `/vector-search`.
+
+Key environment wiring (see `docker-compose.yml` for defaults):
+- `ELASTIC_URL=http://elasticsearch:9200`
+- `ELASTIC_INDEX=this_little_corner_py`
+- `QDRANT_URL=http://qdrant:6333`
+- `QDRANT_COLLECTION=tlc-captions-full`
+- `LOCAL_DATA_DIR=/app/data/video_metadata` (mounted from `./data`)
+
+Mount `./data` (read-only) if you want local fallbacks for metrics; otherwise the app relies entirely on Elasticsearch/Qdrant. Stop the stack with `docker compose down` (add `-v` to clear ES/Qdrant volumes).
