System Extensions¶
Documentation of extensions managed within the core repository directly
and maintained by the core team and core contributors are called
system extensions. If working with the full core package, these
extensions can be found in typo3/sysext directory.
Some of these extensions provide documentation, too. These are listed here.
EXT:core, EXT:backend and other system extensions do not have their own documentation; the functionality is documented in TYPO3 Explained.
