 Adding a document triggers this extension to send an email built from the document's fields. The document's top-level fields specify the email sender and recipients, including `to`, `cc`, and `bcc` options (each supporting UIDs). The document's `message` field specifies the other email elements, like subject line and email body (either plaintext or HTML)

 ```js
 admin.firestore().collection('mail').add({
-  to: ['someone@example.com'],
+  to: 'someone@example.com',
   message: {
     subject: 'Hello from Firebase!',
     html: 'This is an <code>HTML</code> email body.',
   },
 })
 ```
 
-Because each email is built from a Cloud Firestore document, you can reference information stored in _other_ Cloud Firestore documents and fields, like image URLs.
-
 You can also optionally configure this extension to render emails using [Handlebar](https://handlebarsjs.com/) templates. Each template is a document stored in a Cloud Firestore collection.
 
-When you configure this extension, you'll need to supply your **SMTP credentials for mail delivery** and specify the Cloud Firestore collection where you'll add documents. If you want to use templates, you'll also need to specify the collection containing your template documents.
