To use Docker, you'll need either Docker Desktop or Docker Toolbox installed and setup based on your system.
You'll also need to prepare a local version of the project with a copied base ROM (see steps 2 and 3 of the Linux instructions).
From the root of your local project, run the following command:
docker-compose up --build
This should immediately begin steps 4 and 5 within the Docker container.
To exec into the oot Docker image at any time, run the following command either during or after the build:
docker-compose exec oot bash
