TYPO3 is a content management system (CMS) that you can call up with your browser. The application is compatible with any browser platform, so you can use any browser you like. The IMT offers the use of the open source content management system TYPO3 for maintaining websites. Editors need a Uni-Account.
If you replace the "www" with your hostname in the above address, the so-called "frontendediting" will also work. This means that icons for editing the content are displayed directly on the website. For example, if your web pages to be maintained are accessed via the address https://chemie.uni-paderborn.de, then log in via the URL https://chemie.uni-paderborn.de/typo3.
