 First, we will need to set environment variables. We can do so by setting them in our `.env` file (create it if it's not there). You can also read more about [environment variables](https://www.twilio.com/blog/2017/01/how-to-set-environment-variables.html) from the linked twilio blog. You'll find a sample of what this file will look like in `.env.example`
 
 > IMPORTANT: MAKE SURE YOU'D DONT EXPOSE THE KEYS YOU PUT IN THIS `.env` FILE. By that, I mean don't push them to a public repo, and please try to keep them keys you use in development not associated with any real funds.
