Heroku push giving me "no Cedar-supported app detected error"

Question

I'm trying to push my RoR to Heroku for the first time (I'm a newbie on this stuff!) The error that I'm getting is:

-----> Heroku receiving push
 !     Heroku push rejected, no Cedar-supported app detected

To git@heroku.com:calm-retreat-9405.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@heroku.com:calm-retreat-9405.git'

Answer 1

Double check if you committed correctly your Gemfile and config.ru
