TYPO3 is the leading Enterprise Open Source CMS. Open Source means TYPO3 is published under public license, so you don’t have to pay a fee for using it. On the other hand, everyone can contribute to TYPO3, which is how it lives and thrives. The biggest advantage of using a CMS (content management system) for your website is the ability to control your content separately from the layout or design. With a powerful CMS like TYPO3, you can add, change, and remove text, images, and plug-ins on your site without installing any proprietary software or paying a third-party. Because of the simple administration and editing tools in TYPO3, you can run and edit any kind of site, personal or business, without learning HTML, CSS, programming, or web design. There are other CMS solutions out there, of course, but TYPO3 has some unique features that make it a great option for websites of any size, from small to enterprise:
