Hi @GregBrimble @WalshyDev
I just tweaked this a bit for grammar. Can you check for accuracy / that it makes sense to add? Then, I can merge. Thanks!

@capaj Thank you for the feedback about how we can make improvements with developers.cloudflare.com documentation. I consulted with the engineers on this product and it was determined that the addition of these comments won't be necessary. I'm going to close it now, but feel free to open a new issue or ask any questions.
