-<p class='note warning'>
-As of May 24th 2018 [NMA has shut down](https://notifymyandroid.com/), this was due to the new GDPR european regulations. 
-</p>
-
-The `nma` platform uses [Notify My Android (NMA)](http://www.notifymyandroid.com/) to delivery notifications from Home Assistant to your Android device.
-
-Go to the [NMA website](https://www.notifymyandroid.com) and create a new API key. If you are using the trial offer then keep in mind that your limit is five messages per day.
-
-To add NMA to your installation, add the following to your `configuration.yaml` file:
-
-```yaml
-# Example configuration.yaml entry
-notify:
-  - name: NOTIFIER_NAME
-    platform: nma
-    api_key: ABCDEFGHJKLMNOPQRSTUVXYZ
-```
-
-Configuration variables:
-
-- **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`.
-- **api_key** (*Required*): The API key for NMA.
