 ### Detection
 
-This builder will be auto-detected in either the following cases:
-
-- The `DOKKU_CNB_EXPERIMENTAL` app environment variable is set to `1`.
-
-    ```shell
-    dokku config:set --no-restart node-js-app DOKKU_CNB_EXPERIMENTAL=1
-    ```
-
-- A `project.toml` file exists in the root of the app repository.
-    - This file is consumed by `pack-cli` and used to describe how the app is built.
