Use doctype to specify the document type of the generated markup.

For modern HTML, the usual choice is:

doctype html

This produces:

<!DOCTYPE html>

The selected doctype can also influence how Jade renders elements such as self-closing tags and boolean attributes.

Custom doctypes

Custom declarations can also be written when a specific document format requires one.

doctype html PUBLIC "-//W3C//DTD XHTML Basic 1.1//EN"

For most modern websites, doctype html is the simplest and preferred choice.
