I often forget steps and wish there was a quick instructional guide on deploying a django project on Heroku.
How to Install and Deploy a Django app on Heroku?
I have posted a step-by-steps answer for steps that have worked for me.
In my other answer, the process is well described, but takes time. So I have made a ready installation that is good to go in less than 15minutes.
