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
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. For Extbase and Fluid, please see Developing TYPO3 Extensions with Extbase and Fluid.
