Is the documentation out of date?

I'm trying to get Fastly setup for a Drupal 7 build.

The example.vcl included in the module seems to be outdated according to this thread:
https://www.drupal.org/project/fastly/issues/2871235 →

The example file works, but the real client IP isn't logged in Drupal.
It gets a Fastly IP.
What steps are needed to get that working?

The "Upload VCL" option in the dashboard failed also with the error:

Condition data not properly set.

I tried to manually add the VCL snippets, but the snippets did not seem to take effect.

The README says:

In addition to these snippets you need to add a request setting

- Action: Pass
- Condition: req.http.X-Pass == "1"

But there's no where to enter the condition.
Maybe the Fastly interface has since changed?

I have no idea where to start...
Any guidance would be appreciated.

Thanks
