-The ``seleniumbase mkdir [NAME]`` command creates a new folder with some sample tests you can run. If you wish to use a different browser, you can use ``seleniumbase install [DRIVER]`` with other drivers such as ``edgedriver`` (Microsoft Edge) or ``geckodriver`` (Firefox). Then use ``--browser=edge`` or ``--browser=firefox`` to run tests on that browser (assuming you already have that web browser installed). ``--browser=chrome`` is the default option if not specified.
