I know that there are more detailed instructions that come with the install that should appear in your browser once you've started things up on your computer, but I can give you a few basic pointers here. Feel free to ask about anything specific you're stuck on. Since you've already installed the desktop component and the iPad app, I'll skip mentioning that.
Really that's about it. Your iPad should connect to the desktop and the iPad will synchronously browse to the same pages as you do in Chrome. You ought to be able to remotely inspect the DOM on the device and should be able to take snapshots of any pages shown on your iPad.
Let us know if you have any questions,
