View Existing Configuration =========================== To familiarize yourself with the configuration, look at the existing configuration in your TYPO3 website: To view the existing RTE presets in the "Global Configuration", go to :guilabel:`System > Configuration` in the backend, choose :guilabel:`$GLOBALS['TYPO3_CONF_VARS'] (Global Configuration)` and select :guilabel:`RTE`: .. figure:: images/global-configuration-rte.png :class: with-shadow Global Configuration: RTE > Presets By default, TYPO3 is shipped with three configuration presets: * default * full * minimal Minimal Example =============== Here is a very minimal example of changing the default configuration. All configuration is done in a custom sitepackage extension, see also :ref:`best-practice-sitepackage`. Override the configuration preset "default" by adding this in :file:`/ext_localconf.php` (replace `my_extension` with your extension key): .. code-block:: php $GLOBALS['TYPO3_CONF_VARS']['RTE']['Presets']['default'] = 'EXT:my_extension/Configuration/RTE/Default.yaml'; Add the file :file:`Configuration/RTE/Default.yaml` to your extension, use the file :t3src:`rte_ckeditor/Configuration/RTE/Full.yaml` as example. We explain the example :file:`Minimal.yaml` from the Core: .. literalinclude:: _Quickstart/_Minimal.yaml :language: yaml :caption: EXT:rte_ckeditor/Configuration/RTE/Minimal.yaml :linenos: line #2 Imports existing files to make basic parts reusable and improve structure of configuration line #9 toolbar See `toolbar `__
