Talk:How Metro Works
I recommend integrating this content into the Metro main page. We are missing a basic introduction to Metro there - a defintion of what it is, etc.
Basic introduction is not needed, the goal of the article is to dive deeper in the subject and this would add redundancy, those who read the article know what metro is. At worst I will put cross a reference (best practice : do cross references, do not repeat the text between articles). Metro is not a single article, it is a set of several articles (this one, the quick start guide, the data modules, used and whatever else added in the future) grouped with the category "Metro"and this what the Metro page refers to :)
However I agree with you, Metro need a bit more verbosity, I would make the Metro main page more verbose with a list of several sub pages dedicated to a particular subjects. This page is the common denominator of every other.
