What really happens after `git push heroku master`

Here's my best guess (using a Django app as the example):

    -----> sleep 5
    -----> Python app detected

    -----> sleep 5
    -----> Installing dependencies with pip

    -----> sleep 5
    -----> Preparing static assets

    -----> sleep 5
           Running collectstatic...

    -----> sleep 5
           N static files copied.

    -----> sleep 5
    -----> Discovering process types

    -----> sleep 5
           Procfile declares types -> web

    -----> sleep 5
    -----> Compressing... done, N.0MB

    -----> sleep 5
    -----> sleep 5
    -----> Launching... done, vN

    -----> sleep 5
