confusing documentation regarding APP_NAME

[mrooney]

The README says:

Add an empty file called .static to your root directory of your web project (regardless if you use a custom value for NGINX_ROOT)

Where $APP_NAME is your application's name.

The second sentence doesn't seem to make much sense. What APP_NAME? Where does it go? Am I missing something? :)

Sorry, old docs. Thats unrelated to anything at this point, it was pointing to the manual way of setting this buildpack.

Thanks for the quick fix :)
