+## Calling Composer commands
+
+To call Composer commands, you can use `@composer` which will automatically
+resolve to whatever composer.phar is currently being used:
+
+```json
+{
+    "scripts": {
+        "test": [
+            "@composer install",
+            "phpunit"
+        ],
+    }
+}
+```
+
+One limitation of this is that you can not call multiple composer commands in
+a row like `@composer install && @composer foo`. You must split them up in a
+JSON array of commands.
