-# Enable autorun
+This module enables autorun functionality so you can add policy files to `services/autorun` and tag bundles with `autorun` causing them to be automatically discovered and run.
 
-Simple module to enable autorun functionality, using def.json.
+A policy file you add to `services/autorun` could look like this:
+
+```cfengine3
+bundle agent my_example
+{
+  meta:
+    "tags"
+      slist => { "autorun" };
+  reports:
+    "Hello, world!"
+}
+```
+
+With autorun enabled, the policy file would be parsed, and the bundle evaluated without editing any of your existing files / policy.
+
+It uses the augments file to achieve this, it is the same as editing your `def.json` file like this:
+
+```json
+{
+  "classes": {
+    "services_autorun": ["any"]
+  }
+}
+```
