server.properties problem :(

[waheedullahkhan001]

I do not know how to edit that server.properties
i did clone my app using heroku git:clone and then my app name etc but it was empty then i made server.properties in it
and placed online false and it worked for first time (im not sure but build was successful i think) but it did never work again build failed saying something like $ git push heroku master Enumerating objects: 3, done.
