Will it get merged......??

I apologize for the delay in responding.

I appreciate the effort put into this contribution.

I am having some trouble determining if the benefit is worth adding so many files for (6 added, 4 modified all at root level) since it adds a lot of clutter to the code section of the page. If it had only required changing/adding 1 or 2 files, I'd be less reluctant to merge.

I'll offer some alternatives below, but let me know if you think it is essential that all these files appear in the repo.

As an alternative, I may suggest instead adding a file to the docs folder, for example docker.md that explains the steps for setting up these files. Examples of file contents can be included. A GitHub Gist can be used if you think it would be more organized that way.

As far as the instructions in the readme, that could be moved to the docs as well, or placed in a collapsible section similar to the Heroku steps.

The Heroku nginx looks good, seems to run just fine on the review app.

Thanks, I'm happy to hear what you think.
