 If you use `HA_SCREENSHOT_URL_2`, you can also set `ROTATION_2=180`. If there is no `ROTATION_n` set, then `ROTATION` will be used as a fallback.
 You can access these additional images by making GET Requests `http://localhost:5000/2`, `http://localhost:5000/3` etc.
 
+To make us of the array feature in the Home Assistant Add-On, you may use `ADDITIONAL_ENV_VARS`. It expects a format like this to set any additional environment variable:
+
+```yaml
+- name: "HA_SCREENSHOT_URL_2"
+  value: "/lovelace/second-page"
+- name: "ROTATION_2"
+  value: "180"
+- name: "HA_SCREENSHOT_URL_3"
+  value: "/lovelace/third-page"
+```
+
