+To run VMClarity in Docker on your local machine, complete the following steps.
+
+1. Clone the project repository and navigate to the `/installation/docker` folder.
+
+    ```shell
+    git clone https://github.com/openclarity/vmclarity.git
+    cd vmclarity/installation/docker
+    ```
+
+1. Run the following command to start every control plane element with a docker compose file.
+
+    ```shell
+    docker compose --project-name vmclarity --file docker-compose.yml up -d --wait --remove-orphans
+    ```
+
+    > Note: The `image_override.env` file enables you to use the images you build yourself. You can override parameters in the `docker-compose.yml` by passing a custom env file to the `docker compose up` command via the `--env-file` flag. The `/installation/docker/image_override.env` file contains an example overriding all the container images.
+
+1. After Docker has set up the services, you should be able to see the running control plane containers in Docker desktop and start sending HTTP requests to the API server.
