 # Run with Docker
 
-TODO: Add instructions on how to run Aana Apps with Docker.
+We provide a docker-compose configuration to run the application in a Docker container in [Aana App Template](https://github.com/mobiusml/aana_app_template).
+
+Requirements:
+
+- Docker Engine >= 26.1.0
+- Docker Compose >= 1.29.2
+- NVIDIA Driver >= 525.60.13
+
+You can edit the [Dockerfile](https://github.com/mobiusml/aana_app_template/Dockerfile.yaml) if your application requires third-party libraries in os level.
+
+To run the application, simply run the following command:
+
+```bash
+docker-compose up
+```
+
+The application will be accessible at `http://localhost:8000` on the host server.
+
+
+> **⚠️ Warning**
+>
+> If your applications requires GPU to run, you need to specify which GPU to use.
+>
+> The applications will detect the available GPU automatically but you need to make sure that `CUDA_VISIBLE_DEVICES` is set correctly.
+> 
+> Sometimes `CUDA_VISIBLE_DEVICES` is set to an empty string and the application will not be able to detect the GPU. Use `unset CUDA_VISIBLE_DEVICES` to unset the variable.
+> 
+> You can also set the `CUDA_VISIBLE_DEVICES` environment variable to the GPU index you want to use: `CUDA_VISIBLE_DEVICES=0 docker-compose up`.
+
+
+> **💡Tip**
+>
+> Some models use Flash Attention for better performance. You can set the build argument `INSTALL_FLASH_ATTENTION` to `true` to install Flash Attention. 
+>
+> ```bash
+> INSTALL_FLASH_ATTENTION=true docker-compose build
+> ```
+>
+> After building the image, you can use `docker-compose up` command to run the application.
+>
+> You can also set the `INSTALL_FLASH_ATTENTION` environment variable to `true` in the `docker-compose.yaml` file.
