I cloned the repo from the URL mentioned in the dashboard settings in Heroku to a Windows machine. After committing changes, attempting to push to Heroku fails.
=> git push heroku master
fatal: 'heroku' does not appear to be a git repository
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
I followed some instructions from here, and now I am getting
=> git push heroku master
