File extension for Laravel Blade as an 'index' page

My 'homepage' for a Laravel install works great, which is: welcome.blade.php however, my question is - how do I get other basic 'static' pages to work correctly.

My preferred site top level navigation has for example, 'about us', so what I'd like to do is create a directory called 'about us' and then place a similar page as blade.index.php in there but it throws an error.

So, my question is - how do I name the file within a directory within the web application.

Thanks
