 ```
 The first important thing to notice here is the variable notation in `$$path$$.route.js.hbs`. It will be replaced by the name of the path.
 
+This example also shows `$$path$$` used in a folder name - the generated folder names here will replace $$path$$ with
+the name of the path (in kebab-case).
