TYPO3 is a content management system (CMS) like Drupal, Joomla! or WordPress. As a CMS it is very flexible and has almost limitless possibilities for extensions. There are now more than 5000 extensions available, for example for the use on news sites, shops, or discussion forums. Most of these extensions are free, just as TYPO3 is.
TYPO3 can be activated in the Control Panel under “Websites | Applications | Available Applications | Content Management System ” with just one click. The system will then install the program on your webserver and automatically carry out the necessary configurations for you.
TYPO3 is a platform-independent multi-language CMS – and quite complex. That’s why there is a large user community on the Internet providing tips and tricks to assist users, for example through the TYPO3.net-forum. If you don’t know the CMS ropes yet, you should first visit the official TYPO3.org website. There is a lot of valuable information available there, such as the documentation in eight chapters, a detailed wiki as well as 20 tutorial videos. The videos especially are a great help for beginners; TYPO3 basics and first steps are explained clearly and are easily understood.
If you are a bit further along you will find more videos at Wolfgang Wagner’s website. Wagner is a web designer based in Friedrichshafen on Lake Constance. In his TYPO3 Tutorial 2012 (German) he goes one step further to explain more complex tasks– right through to responsive design, which automatically adjusts structure, images, layout and texts to the size of the screen.
There are of course lots and lots of books on the topic if the above is not enough for you. Here are two recommendations; one for beginners, one for everyday use:
