Implement pipenv, and write documentation. #3
Description
This bot should be using the excellent pipenv instead of requirements.txt, but because the former is less known than the latter, it is important that we also write documentation explaining exactly how to get this project set up.
This issue asks that you create a pipfile, then write the documentation in this repos wiki to explain what pipenv is, and how to use it for this project. The article should include the exact commands the user has to run.
Once this is done, CONTRIBUTING.md should be updated with a link to the wiki article.
Please wait for #2 to be merged before attempting this issue. First to claim the issue gets dibs on the pull request.
