How Do I Configure My Tp-Link Wifi Router?

Hello, This is Kevin Edward. I am from Los Angeles, California. I have been working on my startup, I am starting a cheap essay writing service USA and I have bought a Tp-Link Wi-fi Router for the place but I don't know how to configure it & I am currently keeping an eye on by expenses due to which I have to keep my budget tight and can't hire a professional for the configuration. Someone, please guide me on how to do its configuration on my own. I'll be highly thankful to you for your help.
