+# 1. Install [Docker](https://www.docker.com/)
+# 2. Change the current directory to the `firmware/` directory
+# 3. Run `docker compose up --pull=always build-ultra` to build the firmware for the ChameleonUltra
+# 4. Run `docker compose up --pull=always build-lite` to build the firmware for the ChameleonLite
+# 5. The firmware will be available in the `firmware/objects/` directory, you can build only one firmware at once.
