 ## Configuration
 
+### Docker
+
+To modify the build of the used n8n image for the container there are dotenv variables available.
+
+- `N8N_TAG` - The used n8n image tag. Default is `latest`.
+- `N8N_TIMEZONE` - The timezone of the n8n container. Default is `Europe/Berlin`.
+- `N8N_BASIC_AUTH_ACTIVE` - Enable basic authentication. Default is `false`.
+- `N8N_BASIC_AUTH_USER` - The basic authentication username. Default is `n8n`.
+- `N8N_BASIC_AUTH_PASSWORD` - The basic authentication password. Default is `n8n`.
+- `N8N_ENCRYPTION_KEY` - The encryption key for sensitive data. Default is `n8n`.
+
+Use the ddev dotenv command to set these variables.
+
+```bash
+ddev dotenv set .ddev/.env.n8n --n8n-tag=1.50.0
+```
+
 ### n8n Settings
 
 Settings are in general defined in the file `.ddev/docker-compose.n8n.yaml` via environment variables.
