 ## Local setup
 
-We provide a docker container for our documentation to make it easy to work on docs with a real-time preview. Once you install [Docker](https://docs.docker.com/engine/install/) and [Docker Compose](https://docs.docker.com/compose/install/), do the following to get a live preview:
-
-1. Create a dummy `.env` file
-
-   ```{code-block} sh
-   touch .env
-   ```
-
-2. Create a dummy federation network
-
-   ```{code-block} sh
-   sudo docker network create federation
-   ```
-
-3. Build the container
-
-   ```{code-block} sh
-   sudo docker compose -f dev.yml build docs
-   ```
-
-4. Run the container
-
-   ```{code-block} sh
-   sudo docker compose -f dev.yml up docs
-   ```
+We provide a fully automated setup for a local live-preview of your changes. Make sure you meet the requirements outlined above and run `make dev`.
