Needs summary

By de­fault, a page’s sum­mary (that shows up in the popover when a user hov­ers over a green­link) is the page’s first para­graph. Some­times the first para­graph is not well-suited for a popover sum­mary. Add this tag to pages that need to have a cus­tom sum­mary.

Some pages may re­quire an ac­cessible, tech­ni­cal, or brief sum­mary.
