+Installation with Composer
+==========================
+
+Check whether you are already using the extension with:

+..  code-block:: bash
+
+    composer show | grep impexp
+
+This should either give you no result or something similar to:

+    typo3/cms-impexp       v12.4.11
+
+If it is not installed yet, use the ``composer require`` command to install
+the extension:

+
+    composer require typo3/cms-impexp

+Installation without Composer
+=============================
+
+In an installation without Composer, the extension is already shipped but might

+
+#.  In the backend, navigate to the :guilabel:`System > Extensions`
+    module.
+#.  Click the :guilabel:`Activate` icon for the Import / Export extension.

+
+======================================================
+Introduction into the system extension "Import/Export"
+======================================================
+
+The system extension "Import/Export" (EXT:impexp) allows content to be exported
+from one installation of TYPO3 and then imported into another. Exported data
+includes content from multiple tables including :sql:`tt_content` as well as
+images and other files stored in :directory:`fileadmin/`.
+
+This extension is often used to manage content for :ref:`distributions <t3coreapi:distribution>`
+and also training and demonstration purposes.
+
+..  _merging_multiple_sets_of_data:
+
+Merging multiple sets of data
+=============================
+
+By default the identifiers are changed when importing data, making it possible to
+merge several projects into one installation. The table identifiers are
+automatically changed in such a way that content elements remain attached to
+their pages and images to their content elements.
+
+It is also possible to keep the identifiers (`uids`) to allow the reproduction
+of the exact same page and content tree.
+
+..  _what-doesnt-it-do:
+
+What doesn't it do?
+===================
+
+*   Exported content does not include code from any installed extensions or
+    sitepackages.
+*   This extension is not used for the :guilabel:`Download`
+    feature in the :guilabel:`List` module.
+
+..  _backward_compatibility:
+
+Backward compatibility
+======================
+
+The data structure for content exports have seen very little changes since their
+original inception. It is sometimes possible to export content from a fifteen
+year old TYPO3 installation straight into a current installation of TYPO3.
+
+It is often more feasible to use the import/export tool
+than it is to attempt to update old installations of TYPO3.
+
+The following images show the export dialog of a current TYPO3 installation and
+TYPO3 v3.8.0: They correspond pretty much.
+
+However, several details may change due to Deprecations and Breaking Changes,
+which can lead to issues with old import data. In cases where the import fails,
+it is recommended to try to manually export assets/files, and re-create the
+reference Index after import. The older an installation is, the more manual
+rework is expected.
+
+Ongoing improvements to the Import/Export code base can only made, when
+legacy considerations are not the first priority. A "guaranteed" fully-working
+export and re-import is only given for T3D structures within the same
+major version.

+
+=========================================
+Security considerations regarding exports
+=========================================
+
+Exported content in TYPO3 can contain sensitive or restricted information that
+needs to be properly secured. This document outlines the recommended best
+practices for managing the security risks associated with exporting content.
+The following sections explain:
+
+-   Why you should **disable the export extension when not in use** to reduce
+    the risk of unintentional data exposure.
+-   How to **prevent unauthorized access** by restricting the visibility of
+    export options in the TYPO3 interface.
+-   Why it is important to **secure the export directory** to block unauthorized
+    file access on different webserver setups.
+-   How to **report a security issue** to the TYPO3 Security Team if you
+    identify vulnerabilities not addressed in this guide.
+
+..  contents:: Table of contents
+
+..  _security-disable-extension:
+
+Disable the extension when not in use
+=====================================
+
+Exported content may contain sensitive and restricted information related to
+your site. It is recommended that this extension be deactivated when it is not
+in use to prevent content being exported in error.
+
+..  _security-prevent-unauthorized-access:
+
+Prevent unauthorized access
+===========================
+
+The export function is available by default for editors without admin rights.
+It is limited to content to which the editor has access. The export
+functionality can be hidden in the editor's context menu by using the user
+TSconfig setting :ref:`contextMenu disableItems
+<t3tsref:useroptions-contextMenu-key-disableItems>`.
+
+Note that it cannot be completely disabled as there are currently other entry
+points.
+
+..  _security-secure-export-directory:
+
+Secure the export directory
+===========================
+
+Exports are stored in :path:`fileadmin/user_upload/_temp_/importexport/`.
+TYPO3 will automatically create a :file:`.htaccess` file to prevent access to
+this folder from external sources. On Nginx webservers, the :file:`.htaccess`
+file has no effect. Follow the :ref:`Security guidelines for System
+Administrators <t3coreapi:security-administrators>` to find out how to prevent
+access to specific directories on Nginx webservers.
+
+..  _security-reporting-issue:
+
+Reporting a security issue
+==========================
+
+If you believe you have found a security-related issue that is not listed
+here, please contact the :ref:`TYPO3 Security Team <t3coreapi:security-team>`.

+======================================================
+Using the Import/Export tool from the command line
+======================================================
+
+The import/export tool can alternatively also be used via the command line.
+The advantage of using the CLI is that there is no PHP time limit, therefore
+larger page trees can be exported and imported.
+
+The exports and imports can be fine-tuned through the complete set of options
+also available in the :ref:`import <import>` or :ref:`export module <export>`
+of the TYPO3 backend.
+
+.. note::
+
+    If your TYPO3 installation is based on Composer, you can run the command
+    with the shortcut :bash:`vendor/bin/typo3` instead of
+    :bash:`typo3/sysext/core/bin/typo3`.
+
+..  attention::
+
+    Exporting and importing content may expose sensitive data or bypass
+    permission boundaries. Review the :ref:`security considerations regarding

+======================================
+How to use the Import/Export extension
+======================================
+
+The import/export tool can be accessed via the :ref:`TYPO3 backend<export>` or
+the :ref:`command line<command_line>`.
+
+Users with admin rights can use both the import and the export functionality.
+Editors with no admin rights can only use the export functionality (unless
+it is disabled). Editors can only export content they have access to.
+
+The import functionality can be used for :ref:`content updates<content-update>`
+instead of importing the entire page tree and its content.
+
+The export functionality can be used to export initial content for use in
+:ref:`distributions<t3coreapi:distribution>`.
+
+It is also possible to save and load export data :ref:`presets<presets>` for
+recurring export jobs.

+
+Any configuration settings made in the :ref:`export module <export>` are not
+saved automatically. To reuse export configurations, you need to save them
+as presets.
+
+Presets are stored internally in the :sql:`tx_impexp_presets` table and can
+be included in export files by adding this table to the export.
+
+..  contents:: Table of content
+
+..  warning::
+
+    If you have manually excluded records from export, the :sql:`uid` values of
+    those exclusions are saved in the preset. This can lead to unexpected
+    exclusions if you reuse the preset in another TYPO3 instance.
+
+    Therefore, review the excluded records in the "Configuration" tab
+    thoroughly when you load a preset.

+Saving a new preset
