+## usage
+The default game is run by simply executing the `tetris` command.
+If the unicode characters look a bit
+wonky in your terminal, you can also run
+```shell
+tetris --ascii-only         # uses [] as preview cell
+# or
+tetris --preview-chars 'XX' # uses custom characters as preview cell
+```
+If you always play on level `6` and want to skip the prompt, you can start the game immediately via
+```shell
+tetris --level 6
+```
+Lastly, to see the current highest score, you can run `tetris --high-score`.
+And of course, see `tetris --help` for help.
