Search Chromecast in the app store to see a list of available apps.
Once you have a compatible app, setup your chromecast by plugging it into your TV. (Both the key itself, and the USB power cable) change your TV input to the input you plugged your chromecast's key into. Make note of the name it gives your chromecast. Once connected to your WiFi and setup, open the chromecast app on your phone or device. It should pop up and ask you to connect to your chromecast. Once connected open a compatible app and click the chromecast streamer. It looks like a rectangle with a WiFi symbol in the lower left corner. Your TV should now show the main page for your app! Whala!
Have fun streaming using your Chromecast!
