To customize your site, you override the files that produce the site's default look and content with files you have edited to produce your preferred look and content.
You can change many aspects of your site's appearance and behavior, including fonts, colors, icons, standard email content, and even certain elements of the application's functionality, to fit in with your organization's preferred visual appearance and content. This is known as "branding" your site.
You override a particular file by committing your modified version of that file into a special Subversion repository called branding, in a special project called look. To do any branding, you will need to have commit access to this repository in the look project.
CollabNet provides downloadable zip files containing the default, original versions of these files.
