very simple device

(yes it comes with directions)

Plug it into a tv hdmi port and power it via USB or the provided wall wart

Download the chromecast app to your PC or android device. Have wireless on and the app will find your chromecast. Follow the directions on the screen to name it and get it talking to your homes wifi. From there anytime you want to cast click the chromecast button on the screen and it will go to your TV with that device plugged in. You can have multiple chromecasts.

I have one hooked up to my stereo so I can stream music wireless from google play or pandora.
