just --list
Available recipes:
    compose +ARGS="up -d --no-recreate" # Bring up the example services with docker/podman compose
    coverage                            # Run unit tests with coverage and open the HTML report
    default                             # Start the example services via compose and run the blueapi server
    init-example-services               # Clone the example-services submodule if needed but leave it alone otherwise
    lint                                # Regenerate schemas, run pre-commit checks and type checking
    repl                                # Start an interactive REPL logged in to a blueapi client
    run PLAN PARAMS                     # Run a plan against the blueapi controller
    serve *OPTS                         # Run the blueapi server against the system test config
    system *OPTS                        # Run the system test suite
    unit *OPTS="-n logical"             # Run the unit test suite

Shows docs. I have example a vscode plugin which has made some spacing changes.

I have also added just to completion in dev-container for ease of use

The docs are good, thanks for adding them, mainly insure what should be here vs in the upstream projects.
