SDL Tridion

Tridion is a Content Management System (CMS), a program which allowes users to organize, edit, and publish web content. CMS's are used to maintain websites and generally do not require knowledge of HTML to make most site updates. Because Tridion is web-based, you can access it through your web browser rather than opening an application on your computer like Outlook or Excel. In the following guide, you will learn how Tridion organizes pages and contents and how to navigate Tridion.

Accessing Tridion

You need to use a web browser (e.g. Mozilla Firefox, Google Chrome, Internet Explorer, or Safari) to access Tridion. The program will only be "open" in the tab or window that you are using Tridion. Tridion operates best on Mozilla Firefox and Google Chrome. If necessary, Explorer 8.0 or higher or the latest version of Safari can be used, but Tridion runs slower on these browsers.
