+# Drone Discord Webhook
+
+This is a plugin for the [Drone CI/CD](https://www.drone.io/) tool which purpose is to post messages after each builds completed or failed.
+
+## How to use it?
+
+There are 3 environment variable that can be set.
+
+(Required) `WEBHOOK_URL`: The url of the webhook that will send the status message
+
+(Optionnal) `AVATAR`: Url of an image that'll be used for the webhook user.
+
+(Optionnal) `USERNAME`: Username of the avatar that'll be assigned to the webhook.  
+
+```yaml
+- name: Send discord notification
+    image: r.regnault.dev/drone-discord-webhook
+    environment:
+      AVATAR: "Optionnal webhook avatar url"
+      USERNAME: "Optionnal webhook username"
+      WEBHOOK_URL:
+        from_secret: WEBHOOK_URL
+    when:
+      status: [ success, failure, changed ]
+```
+
+## How does it look?
