This is an outline - I might have left-out a minor step or two...
Start with the [u]Getting Started Page[/u].
Download and install the [u]Development Environment[/u].
Open the [u]Blink Example Sketch[/u]. (It should be on your hard drive in the Examples folder after installing.)
Connect your Arduino to your USB port.
Compile and upload Blink into your Aduino.
The Blink program should run, and you should see the green Pin-13 LED blinking.
