Confusing guide + 404 on linked blog post page

Problem/Motivation

I have no idea how to map the fields that Google Ad Manager gives you, and outputs when you generate tags, to the options that the module gives. The details listed make no sense to me at all.

Steps to reproduce

On module page on drupal.org

Proposed resolution

Illustration mapping what one sees here:
https://admanager.google.com/XXXXXXXX#inventory/ad_unit/create
And here:

to what the DFP module will offer
/admin/structure/dfp/tags/manage/XXXXX?destination=/admin/structure/dfp/tags
I cannot conceive of how to make the two work together at all.

You can see how different the output is from what I place as per Google's generated tags, and what the DFP module provides here:

Remaining tasks

User interface changes

API changes

Data model changes
