+Send notifications via e-mail
+=============================
+
+[◀ Go back to main README](../../README.md)
+
+> ℹ️️ **Info**: This module can not be used on its own but requires the base
+> installation. See [main README](../../README.md) for details.
+
+Description
+-----------
+
+This module adds support for sending notifications via e-mail. A queue is
+used to make sure notifications are not lost on failure but sent later.
+
+Requirements and installation
+-----------------------------
+
+Just install the module:
+
+    $ScriptInstallUpdate mod/notification-email;
+
+Also you need a valid e-mail account with smtp login credentials.
+
+Configuration
+-------------
+
+Set up your device's
+[e-mail settings](https://wiki.mikrotik.com/wiki/Manual:Tools/email).
+
+Then edit `global-config-overlay`, add `EmailGeneralTo` with a valid
+recipient address. Finally reload the configuration.
+
+### Sending to several recipients
+
+Sending notifications to several recipients is possible as well. Add
+`EmailGeneralCc` on top, which can have a single mail address or a comma
+separated list.
+
+Usage and invocation
+--------------------
+
+There's nothing special to do. Every script or function sending a notification
+will now send it to your e-mail account.
+
+But of course you can send notifications directly or use a function in your
+own scripts. Give it a try:
+
+    $SendEMail "Subject..." "Body..."
+
+Alternatively this sends a notification with all available and configured
+methods:
+
+    $SendNotification "Subject..." "Body..."
