Getting index of files

[thany]

I just ran composer create-project wardrobe/wardrobe as per the instructions, and then went to the website with my apache. Since there's no .htaccess, it displays an index of files. So... That works. But wardrobe doesn't do jackall - I have to make it 'go', somehow, so at this point (and this might be worth putting in the install instructions), which file are we supposed to run to install wardrobe further?

One thing I've tried is to go to server.php, because it's the only php file that might be runnable. It redirects to /install which (correctly) outputs a 404 - it doesn't exist, neither as a file, nor as a directory.

What's the next step?
