+# DEMO: MONAI Deploy App SDK App Runner Integration
+
+This demo shows how an application integrates with the MONAI Deploy Informatics Gateway (MIG) by subscribing to events emitted by MIG and launches the configured MONAI Deploy Application Package (MAP).
+
+
+![Demo-AppRunner](./demo-apprunner.png)
+
+## Requirements
+
+- MONAI Deploy Informatics Gateway 0.1.0+
+- MONAI Deploy App SDK 0.2.1+ with [dicom_series_to_image_app](https://github.com/Project-MONAI/monai-deploy-app-sdk/tree/main/examples/apps/dicom_series_to_image_app) built as `dcm-to-img:latest`
+- RabbitMQ configured and running
+- MinIO configured and running
+- Python 3.7+
+
+
+## Running the demo
+
+1. Install requirements specified above
+2. Install python dependencies specified in [requirements.txt](./requirements.txt)
+3. Edit `config.json` and change:
+   1. `endpoint`/`host`, `username`, and `password` for both storage and messaging services
+   2. `bucket` where payloads are stored
+   3.  `application` to point to the correct MAP
+4. python app.py
+
+**Notes**: For MONAI Deploy App SDK 0.2.1, set `ignore_json` to false in the `config.json` file so DICOM JSON files are not downloaded.
+
+## Tips
+
+- Try another MAP by changing `application` in the `config.json` file.
+- Instead of calling App Runner, integrate with [MIS](https://github.com/Project-MONAI/monai-deploy-app-server)
