LGTM: I assume MyF5 is permissible about gerunds.

Actually, no. @travisamartin shared their style guide internally. But based on my reading and SME reactions, the content is still helpful and accurate. So it's valid to link to the article

So I'm going to follow up with suggested changes to the actual article.
