+# 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 0.1.1+
+- MONAI Deploy App SDK 0.2.1+
+  - A MAP from the [examples](https://github.com/Project-MONAI/monai-deploy-app-sdk/tree/main/examples/apps/) or BYO MAP.
+- RabbitMQ configured and running
+- MinIO configured and running
+- Python 3.7+
+
+
+## Running the demo
+
+1. Install requirements specified above
+2. Configure an AET with one or more workflows. For example, the following command would trigger the `dcm-to-img:latest` MAP.
+    ```
+    mig-cli  aet add -a DCM2PNG -w dcm-to-img:latest -v
+    ```
+3. Install python dependencies specified in [requirements.txt](./requirements.txt)
+4. Edit `config.json` and change:
+   1. `endpoint`/`host`, `username`, and `password` for both storage and messaging services
+   2. `bucket` where payloads are stored
+5. 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.
+
+## Job Directory Structure
+
+Both retrieved input dataset and MAP generated output are stored under the `jobs/` directory which is configurable in the
+`config.json` file under `working_dir`.
+
+A subdirectory is created for each request received using the `correlation_id` specified in the payload.
+Given that one or more workflows can be specified in the payload, output generated from each MAP is stored under `jobs/{correlation_id}/output/{map_name}`.
+
+Sample output of `jobs` directory:
+```
+└── db61c4fc-b84e-4255-b40a-60254f93ca6f (correlation_id of the request)
+    ├── input
+    └── output
+        └── dcm-to-img-latest (name of the workflow/MAP)
+```
+
+## Other Ideas
+
+💡 Instead of calling App Runner, integrate with [MIS](https://github.com/Project-MONAI/monai-deploy-app-server)
