@falcone OK I want to know where to add any file that has end point like .php

@falcone and where can I change the jcow name to my own website name.

@falcone and how to change my copy right to my own and change my template colour to my own choice

@tugadar you can make changes in your admin panel/ general settings. you own sitename -> sitename, copyright -> footer message

@tugadar for own colors make a new theme or change an exiting theme. example themes/default

@tugadar in the theme you can change home.tpl.php, page.tpl.php and page.css

@tugadar https://www.jcow.net/docs/?s=themes

@tugadar for own plugins check here https://www.jcow.net/docs/?s=apps_development

@falcone can I add third party modules to my site
