Now that you've got your shell, it's time to make some noise!
Locate the shell's power button, usually marked with a menacing red "ON" sign. Press the button, and the shell will begin to glow with an otherworldly energy.
As the shell's power grows, it will start to emit a piercing whine, like fingernails on a chalkboard. This is normal. Do not be alarmed.
With the shell activated, you'll be able to access a whole new world of shell-based functionality. But don't get too cocky - the shell is temperamental, and can turn on you at any moment.
