# 3 Steps to Pro WebRTC for Beginners
WebRTC today is deep and invovled with many subtleties which are easy to miss. We built a WebRTC SDK which solves these challenges and will allow you to become a Pro **WebRTC app developer**. In three easy steps you'll find yourself with the key basics for building business ready WebRTC applications.
1. Get PubNub Keys
1. Create a Dialer and Call Receiver GUI

## WebRTC SDP and ICE Packets
Usually when you are building with WebRTC from bare JavaScript, you will need to invent a way to both generate and broadcast two different types of payloads. **SDP and ICE packets** are descriptor packets which explain to your computer a way to communicate over an internet route. The first road block is generating the packets. Once you've generated SPD and ICE, you will need a signalling system like PubNub to exchange these packets between two peers.
- webrtc is hard
- but it shouldn't be
- that is why we created WebRTC SDK that is production ready.
- you'll learn how to build WebRTC Apps in less than 30 minutes.
