The buildpack will detect your app as lwan if it has the file lwan.conf.erb in the conf directory. You must define all listener directives as listener *:<%= ENV["PORT"] %> in order for this buildpack to work correctly.

To start the server run bin/start_lwan. If no Procfile is present buildpack will create one with web: bin/start_lwan
