 A [Drone](https://drone.io) plugin for ntfy.
 
+## Example
 
+The following is an example pipeline where we only send a notification
+
+```yaml
+steps:
+  - name:
+    image: clortox/drone-ntfy
+    settings:
+      URL: https://ntfy.clortox.com
+      USERNAME: drone
+      PASSWORD:
+        from_secret: ntfy_password
+      TOPIC: drone-builds
+      MESSAGE: Drone build done!
+      CLICK: https://drone.clortox.com/tyler/drone-ntfy
+      TITLE: Drone (Drone-ntfy)
+```
+
+A living, breathing example of this is in this repository's [drone file](.drone.yml).
+
+## Options
+
+There are several options that you can configure when sending the notification.
+Note that the `ntfy Name` is the name you will use in the settings section of
+your configuration.
