Goal of this document is to quickly explain how to write a Docbook document. A full documentation can be found at Docbook reference, but more than 300 elements exists... too much to quickly create a document with basic element such as link, parapgraph, graphic, section.... So this document is a short-HOWTO write Docbook with common tag. This document is of course realize in Docbook.
