First of all, make sure you have `browserify` installed as a command in your $PATH. You can do this by running: npm install -g browserify If you get permission errors, try putting `sudo` in front of that command. Once you have browserify installed, write a program that prints the string 'BEEP BOOP' using `console.log()`. Compile your program with `browserify` and pipe the bundle into `$ADVENTURE_COMMAND verify` like this: browserify main.js | $ADVENTURE_COMMAND verify If you just want to run your solution without verifying you can do: browserify main.js | $ADVENTURE_COMMAND run
