if number >=0 && number <= 100 {

This describes the workflow to use Heroku as a staging environment. It assumes you already have an existing heroku app in production.

# rename your git remote heroku to something else like production
git remote rename heroku production

# so now you will push as: git push production master

# create the staging app
heroku apps:create staging-appname
