Before going ahead prepare for the following things:
Charge your device to minimum 70%, that will avoid your device to shut down during the installation process.
Stock recovery must be installed on your device and your device must not be rooted.
The OTA installation is only possible with the help of stock recovery so if you own a device with custom recovery installed, unroot it and install stock recovery on it. The best way to get your device back in stock condition is to flash the stock firmware that was released prior to this upcoming Nougat firmware.
