Sign up for a Vonage account, and check the Getting Started Guide for your API Key and API Secret if you don't already have one.

You'll need to set a few environment variables to a .env file, using .env.example as a template. Simply copy over .env.example to .env, and edit in the values for:

• VONAGE_API_KEY
• VONAGE_API_SECRET
• GMAIL_USERNAME
• GMAIL_PASSWORD - Don't worry, this is not transmitted anywhere.
