+
+The Twilio notify platform enables sending notifications via SMS, powered by [Twilio](https://twilio.com).
+
+### Configuration
+
+```yaml
+# Example configuration.yaml entry
+notify:
+  platform: twilio_sms
+  account_sid: ACCOUNT_SID_FROM_TWILIO
+  auth_token: AUTH_TOKEN_FROM_TWILIO
+  from_number: E164_PHONE_NUMBER
+  # Optional
+  name: NOTIFIER_NAME
+```
+
+Configuration variables:
+
+- **account_sid** (*Required*): Your Twilio Account SID which can be found in your [console](https://www.twilio.com/console). It starts with the letters `AC`.
+- **auth_token** (*Required*): Your Twilio Account SID which can be found in your [console](https://www.twilio.com/console). It should be directly under where you found the `account_sid`.
+- **from_number** (*Required*): An [E.164](https://en.wikipedia.org/wiki/E.164) formatted phone number, like +14151234567. See [Twilio's guide to formatting phone numbers](https://www.twilio.com/help/faq/phone-numbers/how-do-i-format-phone-numbers-to-work-internationally) for more information.
+- **name** (*Optional*): Setting the optional parameter `name` allows multiple notifiers to be created. The default value is `notify`. The notifier will bind to the service `notify.NOTIFIER_NAME`.
+
+### Usage
+
+Twilio is a notify platform and thus can be controlled by calling the notify service [as described here](/components/notify/). It will send a notification to all E.164 phone numbers in the notification **target**. See the notes above regarding the `from_number` configuration variable for information about formatting phone numbers.
+
+```yaml
+# Example automation notification entry

+      event: sunset
