It will be easy for you to connect the Chromecast, and once it is done, you need to connect your TV with the Wi-Fi and then use it.
Once everything is connected, you need to download the Chromecast app, and for that, you need to visit the site and download the application from there.
If you download it, you can just start Chromecast and use it the way you want to and watch anything you wish.
