This example app does not seem to be implemented?

[Antman261]

This app does not match the docs on the website.

I'm currently trying to make sense of this part of the docs:

Step 3: Add the following environment variable

Set environment variable for coverage export. You will not need to access this directory yourself, but the application will read coverage reports from this directory:

export NODE_V8_COVERAGE=codecov_reports

And am aa bit disappointed to see the example app linked in the doc was never completed
