+# Running Rowboat (Headless) in Docker
+
+You can run the core agent logic of Rowboat in a Docker container, suitable for server environments or always-on agents.
+
+## Build
+
+From the `apps/x` directory:
+
+```bash
+docker build -t rowboat-agent .
+```
+
+## Run
+
+You need to mount a volume for the data directory (`~/.rowboat`) to persist your knowledge graph and credentials.
+
+```bash
+docker run -d \
+  --name rowboat \
+  -v $(pwd)/rowboat-data:/data/.rowboat \
+  rowboat-agent
+```
+
+## Configuration
+
+The agent uses the configuration files in your data volume (`/data/.rowboat/config/`).
+If you are starting fresh, you may need to manually populate `models.json` or `config.json` in that volume, as there is no UI to guide you through onboarding in this headless mode.
+
+### Environment Variables
+
+You can inject API keys via environment variables which Rowboat will pick up (if configured to read them):
+
+- `OPENAI_API_KEY`
+- `ANTHROPIC_API_KEY`
+- `GOOGLE_API_KEY`
+```
