+# But First, a Bit of Configuration
+
 To do this magic, you have to first
 
-1) Add an entry for `DOMAINS` in the `.env` file, with comma-separated values (no spaces).
+1) Create an environment variable `NETLIFY_TOKEN`, obtained [here](https://app.netlify.com/user/applications#personal-access-tokens).
+1) Create an environment variable `NETLIFY_DOMAINS`, with comma-separated values (no spaces), if you're planning to use custom domains.
 1) Delegate DNS management of all domains listed in `DOMAINS` to Netlify ([link](https://docs.netlify.com/domains-https/netlify-dns/delegate-to-netlify/))
