 1. Add the following to change your [minimum-stability](https://getcomposer.org/doc/articles/versions.md#minimum-stability) in your project `composer.json`:
 
     ```json
-        "minimum-stability": "dev",
-        "prefer-stable": true,
+    "minimum-stability": "dev",
+    "prefer-stable": true,
     ```

     ```console
-    > composer require codeigniter4/shield:dev-develop
+    composer require codeigniter4/shield:dev-develop
     ```
 
     The above specifies `develop` branch.
