I'm not sure linking to John Papa's style guide is necessarily the best resolution here - there are quite a few developers in the Angular community who dislike certain aspects of that style guide strongly, such as the controllerAs with vm pattern for being semantically opaque & unsearchable in a codebase of any size.

So maybe the text title should change as well.
The current URL linked to does not have the mentioned style guide anymore, but instead itself points to John Papa's style guide.
