What are the steps to deploy a custom build on production?

Hi all, so far I’ve done the following:

  1. Installed Ghost from source

  2. Installed the CLI of Grunt.js

  3. Runned grunt prod and then grunt release (both successful)

Where is the zip file that grun release creates located? I can’t seem to find it. I have an instance running with the default ‘ghost install’ in AWS and I would like to replace it with the one from source that I have on a private repository on GitHub following the documentation steps in step 1 which has some custom changes. Any ideas on how to do that?
