Thanks for the MR.
I updated the inital post to fix the links to the files to update.

@kwigley Any reason you closed the MR?

[kwigley]

Nope, just wanted to make sure I updated docs before submitting PR. I'll reopen and add you're feedback. Thanks!

[kwigley]

@edouard-lopez ready for another look, didn't add any feature tests because this is just looking for an env var, but let me know if you would like me to add one.

[edouard-lopez]

Could you allow push to your fork so I can add the feature tests?

[edouard-lopez]

I had some difficulties pushing to your repo. When I finally managed to do it, I pushed pure/master in your repo/master which closed this PR. And I'm unable to push to your repo anymore.

I created a new PR with your commits in #348
