Deploying to Heroku

1. Install heroku on your system using the official instructions.
2. Do heroku login and follow the instructions.
3. Make sure you're in the oppiabot repository and do heroku git:remote -a murmuring-castle-33250.
4. Make sure you are on the master branch and pull the latest changes from upstream (git pull upstream master).
5. Do git push heroku master, or if it does not work git push heroku master --force (force is fine in this case as we want basically want the latest master deployed and do not care about what was deployed before).
