How to set the summary for a page
You can define the summary of a page on MDN, to be used in various ways, including in search engine results, in other MDN pages such as topical landing pages, and in tooltips. It should be text that makes sense both in the context of the page, and when displayed in other contexts, without the rest of the page content.
A summary can be explicitly defined within a page. If it is not explicitly defined, then typically the first sentence or so is used, which is not always the best text for this purpose.
