 Project N.O.M.A.D. is now installed on your device! Open a browser and navigate to `http://localhost:8080` (or `http://DEVICE_IP:8080`) to start exploring!
 
+### Advanced Installation
+For more control over the installation process, copy and paste the [Docker Compose template](https://raw.githubusercontent.com/Crosstalk-Solutions/project-nomad/refs/heads/main/install/management_compose.yml) into a `docker-compose.yml` file and customize it to your liking (be sure to replace any placeholders with your actual values). Then, run `docker compose up -d` to start the Command Center and its dependencies. Note: this method is recommended for advanced users only, as it requires familiarity with Docker and manual configuration before starting.
+
 ## How It Works
 N.O.M.A.D. is a management UI ("Command Center") and API that orchestrates a collection of containerized tools and resources via [Docker](https://www.docker.com/). It handles installation, configuration, and updates for everything — so you don't have to.
