.. include:: /Includes.rst.txt .. _installation: ============ Installation ============ Before you begin ================ Before you install the extension make sure you have no other editors installed like `rte_ckeditor`. It ships by default with TYPO3 and has to be removed by composer command if you are using composer: .. code-block:: bash composer remove typo3/cms-rte-ckeditor If you're using the legacy installation (without composer) simply go to the extension manager and disable the `RTE CKEditor` extension. Install with composer ===================== This extension is simply installed with one command over the comfortable composer command line: .. code-block:: bash composer require atkins/t3-trix Install without composer (Legacy installations) =============================================== If you're using legacy systems without composer you can install it with the Extension Manager searching for the key :guilabel:`trix`.
