The beauty of this device is that it is driven from any suitable internet device, PC, laptop, tablet or smartphone. No ugly remote control with obscure and meaningless buttons, just a device that you are already using. When you get some great content on your device you can 'cast' it to your Chromecast-enabled TV. Magic.
[Here's my rant, see my later comment at the end. My mistake as it wasn't as ugly as I first thought]
So I excitedly unwrapped the device, noting the USA power plug - no problem if your TV, like mine, has a USB connection as you can use that for power. Plugged it in, grabbed my Nexus 7 tablet, and navigated to the setup website. This transferred me to the Play Store and to the Chromecast app for Android. This is where I got very annoyed. The Play Store won't allow me to install the app because 'the product is not yet available in my country' !!!
Why did you do that Google? I wasn't trying to buy one - I already have one. It is available in my country - it's in the back of my TV. All I want is the software to let me use it. What's the problem with letting me have that? The world isn't going to end if that happens is it?
I got around the problem by using my Windows 7 laptop. Added the equivalent app and away I went. However I can't use my Android tablet for this. I am about to buy an Android smartphone but it won't work on that either. So I am stuck with using my laptop - at least that works. I googled this issue - there are some very complicated ways to get around this involving shuffling Google accounts etc. That's too stupid and dangerous. So I'll just keep muttering under my breath.

[red-faced correction for the rant above - It DOES work with my Nexus 7 - it's just the setup app that is restricted. While that is still stupid at least I can use the tablet with the Chromecast once it has been set up. Joy joy happy happy]
