 ## Usage
-### Execution
+### Execution in docker container (recommended)
+First, install Docker and Docker Compose using the [official install guide](https://docs.docker.com/engine/install/ubuntu/).
+
+Then, clone this repository and go into the project folder
+```bash
+git clone https://github.com/shaoanlu/CBF_QP_safety_filter.git
+cd CBF_QP_safety_filter
+```
+To run the application, build the docker image and launch the container
+```bash
+docker compose up --build
+```
+
+### Execution in local environment
 Run `demo.py` to start the simulation. A simple version w/ code generation is provided as `demo_codegen_osqp.py`.
 ```bash
 python demo.py  # a PyGame window will be spawn
