Did you try this, and did it work?
Now with the latest version, I think I have it working so you can just drop it into a folder and it should all work. Give it a shot. The thing is that it might need some work on the .htaccess file for the URL rewrite stuff. I tried to make it so that it'll work with the "proper" way of pointing a server to the public folder, but if you have to, you can either do the symlink or moving the public folder, or just dropping it in. I had to make a few changes, though, so if you've already got an install, rename the .env file to env.php. I had to override some of the methods in Laravels master bootstrap in order to shift some other directories around, but the main thing was the env file. I still have to fix the installer for a few things.
So grab the latest master, upload it to a folder and then try going to it in the browser and see what happens.
