+// TODO: finish this!
+
+// mention that transport defaults to settings.email.transport
+
+// mention that headers inherits settings.email.headers
+
+// but only if you don't set `headers.useDefaults: false`
+
+// note that is also uses `settings.email.templates` object
+// which can have `dir` string and `options` object for node email-templates pkg
+
+// also document about having `transport` of `settings.email.transport` be an
+// actual transporter already pre-created (possibly with plugins like html-to-text)
