Page TSconfig and User TSconfig, with which you are able to change the behavior of
the backend in parts. You can change labels, hide or show fields, set
permissions and default values. This reference explains which options are available in

TypoScript Reference
The TypoScript Reference describes the different functions
and objects which can be used to configure the frontend output, including the
full page template and the rendering of individual content elements according to
their type.
The TCA Reference is only relevant for developers. It describes the global
array called $GLOBALS[‘TCA’]. This array is a layer on top of the database
tables that TYPO3 can operate on. It is a very central element of the TYPO3 architecture.
