@sambillingham, thanks for your awesome Guide!
This was exactly what I was looking for.
But I have a short question:

Is there a way to add multiple accounts?

I tried it a few different ways, but I keep getting errors, I tried too add the Accounts like this:

const ACCOUNT_NAME =[ 'name1', 'name2']
const ACCOUNT_KEY = ['key1', 'key2']

Hope you can help me solving this problem, gz @davsner !
