To set up your Chromecast, start by plugging the device into your TV. Then, connect the USB power cable to your Chromecast to power it up. Once your Chromecast is plugged in and powered on, you're ready to start casting.
To begin casting, simply tap the Cast button on your mobile or tablet. This button can typically be found in the bottom right-hand corner of the video you're watching. Once you tap the Cast button, select your Chromecast device from the list of available devices, and your content will start playing on your TV.
