TYPO3 is an open source PHP based web content management system released under the GNU GPL. TYPO3 is copyright (c) 1999-2018 by Kasper Skaarhoj.
This document provides a basic introduction to TYPO3.
TYPO3 requires a webserver with PHP and a database (MySQL recommended). Accessing the backend through a supported browser.
Please see the INSTALL.md in this folder in order to set up a basic TYPO3 installation on your webserver.
TYPO3 is a free and open source Content Management Framework. It is released under the GNU General Public License. It can run on several web servers, such as Apache or IIS, on top of many operating systems, among them Linux, Microsoft Windows, FreeBSD or MacOS X.
TYPO3 was initially authored by Kasper Skårhøj and is now further developed by a community of Active Contributors around a small TYPO3 CMS Team.

A Content Management Framework is more than just a content management system, due to the separation of the streamlined core and optional plugins (extensions). TYPO3 has an open API that allows you to extend the frontend (web site) and/or backend (administration) functionalities.
The concept of extensions makes TYPO3 capable of being developed and used in almost any way you can imagine, either by using any of the many extensions which are available for download, or by writing your own.
TYPO3 is based upon PHP and uses a MySQL database. For more information regarding these requirements see the INSTALL.md file in this folder.
Using the Database Abstraction Layer (DBAL) allows one to use TYPO3 with other Database Management Systems, like PostgreSQL, Oracle and MSSQL.
Here is an overview of the most important TYPO3 resources to help you get started:
https://typo3.org is the main project website. It provides up to date official news, information about events, access to downloading the products and extensions.
https://wiki.typo3.org is a collaborative wiki, providing access to all kind of information around the TYPO3 ecosphere.
https://docs.typo3.org/: TYPO3 is one of the most thoroughly documented OpenSource products around, with manuals covering basic tutorials, TypoScript, administration, development, core structure, etc. You should make the time to locate the various documents, and read those that apply to the work you want to do.
The TYPO3 team is using a tool called Slack to openly communicate with each other and with the public. Several teams use Slack as a way to communicate internally and most channels are a welcome place for you to join and get yourself involved.
Slack is nice for short discussions, but when asking questions, most
answers are lost in the noise after a few minutes. To let everyone
profit from an answer, we recommend to ask questions on StackOverflow.
If you like, you can then post a link into the corresponding Slack
channel to raise attention. And please, do not forget to tag your
questions correctly with
TYPO3 (and possibly other tags like
The community and all TYPO3 teams communicate through newsgroups, which can also be accessed through mailing lists and forums. Any of these three ways provide access to the same communication channels:
- Forum (Web): https://forum.typo3.org/
- Mailing Lists (Mail): https://typo3.org/support/mailing-lists/
- Newsgroups (NNTP): news://lists.typo3.org/

TYPO3 is said to be one of the most sophisticated PHP / Internet related applications available, and the more you play with it, the more you will agree.
Due to the advanced level of the code and functionality, a degree of study, time and perseverance is required to fully understand it, and get the best from it. You should keep trying, as we say it's definitely worth it. TYPO3 is the Enterprise Content Management System "for all".
The GPL license allows for developments that are based upon TYPO3 to also be freely available under the GPL. Please remember this, because TYPO3 is about "Inspiring People To Share". If you are making money with TYPO3 you can donate or become a member of the TYPO3 Association.
