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.
Documentation of system extensions in current core version¶
The list of extensions developed directly in the core repository changes from time to time: Some extensions are merged into others, some are integrated, others abandoned from core and maintained at a different place.
The list below is kept in sync with the current development version of the core, the table further below lists extensions that were part of the core and extracted at some point in time.
