Set environment variables as appropriate for your use-case (refer [`.env.example`](https://github.com/serverless-dns/serverless-dns/blob/main/.env.example) file as `key = "value"` pairs, example key/value env in [`wrangler.toml`](https://github.com/serverless-dns/serverless-dns/blob/main/wrangler.toml) and/or [`fly.toml`](https://github.com/serverless-dns/serverless-dns/blob/main/fly.toml) files).
