+    TYPO3 can be installed without using Composer. This method of installation
     is now considered **out of date**, users are strongly encouraged to use the
     :ref:`Composer-based installation instructions <install>`.
 
-Installing on a Unix Server
-===========================
-
-#. Download TYPO3's source package from `https://get.typo3.org/
-   <https://get.typo3.org/>`_:
-
-   .. code-block:: bash
-      :caption: /var/www/site/$
-
-      wget --content-disposition https://get.typo3.org/13
-
-   Ensure that the package is one level above the web server's document root.
-
-   .. note::
-      Make sure to check the :ref:`release_integrity` of the downloaded files.
-
-
-#. Unpack the :file:`typo3_src-13.x.y.tar.gz`:
-
-   .. code-block:: bash
-      :caption: /var/www/site/$
-
-      tar xzf typo3_src-13.x.y.tar.gz
-
-   Note that the `x` in the extracted folder will be replaced with the latest
-   minor number and the `y` by the bugfix number of TYPO3.
-
-
-#. Create the following symlinks in the document root:
-
-
-   .. code-block:: bash
-      :caption: /var/www/site/$
-
-      cd public
-      ln -s ../typo3_src-13.x.y typo3_src
-      ln -s typo3_src/index.php index.php
-      ln -s typo3_src/typo3 typo3
-
-   .. important::
-      Make sure to upload the whole TYPO3 source directory including the
-      :path:`vendor` directory, otherwise you will miss important dependencies.
-
-#. This will then create the following structure:
-
-..  directory-tree::
-
-    *   :path:`typo3_src-13.x.y/`
-    *   :path:`public/`
-
-        *   :path:`typo3_src -> ../typo3_src-13.x.y/`
-        *   :path:`typo3 -> typo3_src/typo3/`
-        *   :file:`index.php -> typo3_src/index.php`
-
-Installing on a Windows Server
-==============================
-
-#. Download TYPO3's source package from `https://get.typo3.org/
-   <https://get.typo3.org/>`_ and extract the :file:`.zip` file on the web server.
-
-   Ensure that the package is one level above the web server's document root.
-
-
-#. Use the shell to create the following symlinks in the document root:
-
-   .. code-block:: bash
-      :caption: /var/www/site/$
-
-      cd public
-      mklink /d typo3_src ..\typo3_src-13.x.y
-      mklink /d typo3 typo3_src\typo3
-      mklink index.php typo3_src\index.php
-
-#. This will then create the following structure:
-
-    ..  directory-tree::
-
-        *   :path:`typo3_src-13.x.y/`
-        *   :path:`public/`
-
-            *   :path:`typo3_src -> ../typo3_src-13.x.y/`
-            *   :path:`typo3 -> typo3_src/typo3/`
-            *   :file:`index.php -> typo3_src/index.php`
-
-
-Completing The Installation
-===========================
-
-After the source package has been extracted and the symlinks created, continue from the
-:ref:`Access TYPO3 via a web browser <install-access-typo3-via-a-web-browser>`
-section of the :ref:`instructions for installing TYPO3 using Composer <install>` to
-complete the installation.
