 To do this, simply run ``./bin/pyodide serve``
 
 This serves the ``build`` directory of the ``pyodide`` project on port 8000.
 
-* To serve a different directory, use the ``--build_dir`` argument followed the path of the directory
-* To serve on a different port, use the ``--port`` argument followed by the desired port number
