In one sentence, describe what the following article is about:

Set your camera to direct towards the subjects it's shooting. Secure its position, either on a flat solid surface or on a tripod. After installation, locate the app on your mobile device and tap on it to launch it. It has an icon with a compact camera lens on it, and the name on the app will be Canon CW. Use the camera's Wi-Fi menu to connect it to your mobile device. Since it has already been linked, setting up the link once again should be easier. The name of your mobile device should also appear under the camera's Wi-Fi menu for easier connection. Back on your mobile device, on the CameraWindow app, select “Perform Remote Shooting” from the main screen. The camera will bring out its lens, and the mobile device will display what the camera sees in real-time. The screen of your mobile device now serves as the screen or viewfinder of the camera. Just like on the camera, you can adjust some settings right on the mobile device before actually taking the shot.  The zoom factor can be adjusted with the horizontal bar at the bottom. The flash and the timer settings can be set with the reverse arrow button on the right side. The display screen can be set by tapping on the “DISP” button found at the top. Once the settings have been set and you're now ready to take your shot, tap the circular button found on the right side of the CameraWindow. The shot will be taken immediately. The picture taken will be stored on the camera's storage card, not on your mobile device.
Position the camera securely. Launch CameraWindow. Connect the camera. Start remote shooting. Adjust the settings. Shoot remotely.
