Urgently needed !!
I need Complete and good documentation of customization for 3 opensource CMS : joomla ,wordpress, drupal
customization would be both theme /template (create our own template/theme ) and php engine (create our own extensions, plugin ,modules, etc )
dont be such a jerk by giving me docs from codex.worpress.org drupal.org or joomla site
i need more than that !! for example if you have experience adding plugin /modules you could include it in the docs
