Stupid / Beginning Questions

I'm somewhat new to arduino and finally found out about libraries. Unfortunately I have looked for instructions on how to create one and how to upload an existing library. So if someone could give me step-by-step instructions on how to get this library i have here sitting on my desktop to something i can use in code. (please dummy-down the instructions).

It would also be helpful if someone could provide me with a small sample code for a robot that uses Ping)))

Arduino 0017
I’m assuming you have the newest software for Arduino. In there, there is a button that lets you open a library and look inside. Coincidentally, there’s a PING))) library included…

Ok Thanks
ok, thanks
