interactively-test-driver from README sounds great but doesn't exist?

i'm attempting to write my first driver and at the step of wanting to bring up a development server with it loaded and test connecting to a database, but stuck. the example here looks great but must be out of date. same with the one in https://github.com/metabase/sudoku-driver#hacking-on-the-driver-locally the "run" alias doesn't seem to exist. https://www.metabase.com/docs/latest/developers-guide/drivers/start doesn't seem to have info on this either what's the latest and greatest for getting my new driver to connect to a database without just dropping it into a production metabase server and hoping the logs are good enough to debug?

Compare the repository README with the interactively-test-driver example and the run alias mentioned in the issue. Check the sudoku-driver hacking guide and the Metabase driver-start documentation for the current local-development workflow. Done means the README explains a working way to run the sample driver and connect it to a database for debugging.
