+<h2>Why choosing a Debian Derivative instead of vanilla Debian?</h2>

+If you have a specific need which is better matched by a Debian Derivative, you could prefer using it instead of Debian.

+<h2>Why Debian package developers should be interrested in derivatives?</h2>
+
+<p>
+Modifications and improvements available in Debian Derivatives are easier to reintegrate into Debian compared to others source because the patch are in the right format and can be watched automaticaly by Debian. It's done with a script comparing packages (more info in the <a href="https://wiki.debian.org/Derivatives/Integration">Derivatives wiki</a>). Debian maintainers have to watch the patches and decide if they are worth adding them back to Debian.
