-Installation (DZGUI 6 legacy)
-==================
-
-Basic runtime dependencies
----------------------------------
-
-If not already installed, the below can be found in your system’s package manager.
-
-If any dependencies are missing when the application starts, it will warn you, so you need not take any preemptive measures here.
-
-- curl
-- jq
-- steam
-- wmctrl or xdotool
-- zenity
-
-.. note::
-    All dependencies are installed out of the box on Steam Deck.
-
-UI dependencies (Python and PyGObject)
----------------------------------------
-.. important::
-    As of version 6.0.0, you must have a valid Python 3.13 and matching PyGObject environment.
-    Depending on your distribution, this may require additional manual intervention.
-
-Arch Linux (vanilla variants)
-^^^^^^^^^^^^^^^^^^^^^^
-You will need the ``python3.13`` package, if it is not already installed.
-
-Install the following build dependencies:
-
-.. code:: console
-
-   sudo pacman -S cmake gcc pkgconf python-cairo
-
-.. include:: venv.rst
-
-CachyOS (Arch)
-^^^^^^^^^^^^^^^^^^^^^^^
-Refer to the build instructions for Arch Linux first.
-The ``python3.13`` package is not available on CachyOS, so it is recommended to
-use ``uv`` to manage Python versions.
-
-.. code:: console
-
-   sudo pacman -S uv
-
-.. include:: venv.rst
-
-Manjaro 26 (Arch)
-^^^^^^^^^^^^^^^^^^^^^^^
-If Python 3.13 is not already available out of the box, refer to the build instructions for :ref:`Arch Linux (vanilla variants)`.
-
-Debian 13 variants
-^^^^^^^^^^^^^^^^^^^^^^^
-Python 3.13 and PyGObject are available out of the box. No additional steps are necessary.
-You can proceed to the :ref:`Installscript`.
-
-Fedora 43 variants
-^^^^^^^^^^^^^^^^^^^^^^^
-Fedora 43 ships with a newer version of Python (3.14), so you must set up Python 3.13 in its own
-virtual environment (venv) to prevent it from conflicting with the system package.
-
-Install the following build dependencies:
-
-.. code:: console
-
-    sudo dnf install cairo cairo-devel cairo-gobject-devel gcc python3.13 python3.13-devel
-
-.. include:: venv.rst
-
-Ubuntu 24 variants
-^^^^^^^^^^^^^^^^^^^^^^
-Ubuntu ships with an older version of Python (3.12). You must install additional dependencies.
-Add the PPA below to add Python 3.13 to your sources:
-
-.. code:: console
-
-    sudo add-apt-repository ppa:deadsnakes/ppa
-
-Install the following build dependencies:
-
-.. code:: console
-
-    sudo apt install python3.13 python3.13-venv python3.13-dev build-essential python3-gi-cairo pkg-config libgirepository-2.0-dev libcairo2-dev
-
-.. include:: venv.rst
-
-Installscript
------------------------
-
-Invoke the command below from a terminal. This script fetches the main DZGUI script from the repository,
-makes it executable, and launches DZGUI's first-time setup. After running this installscript, you will
-have the file ``dzgui.sh`` wherever you invoked the command.
-
-.. code:: console
-
-    curl -s "https://codeberg.org/aclist/dztui/raw/branch/dzgui/install.sh" | bash

+End-users will gain no benefit from using this flag.

 DZG-009: Floating dialogs appear maximized on tiling window managers

 Usage
 =========
-
 It is always advised to have Steam running in the background. DZGUI is meant to run "on top of" Steam.
 
 DZGUI can be launched in one of three ways.
 
 From a terminal
 ------------------
-
+Invoke the command ``./dzgui`` from wherever you downloaded DZGUI to.
-Invoke the command ``./dzgui.sh`` from wherever you downloaded the DZGUI script to.
 
 Launching from a terminal may give more verbose information in the event of a crash, and can be a good way of troubleshooting problems.
 
 From the shortcut shipped with the application
 --------------------------------------------------
+When completing the first-time setup, you will be asked if you want to create additional system shortcuts.
+If applicable for yourDesktop Environment, these shortcuts can be created.
 
-On most distributions, if you are using a desktop environment based on the Freedesktop specification, shortcuts will be installed for you.
+- One shortcut will be located under the ``Games`` category of your system’s applications list/start menu.
-
+- The other is accessed via the ``DZGUI`` shortcut on the desktop
-- One shortcut is located under the ``Games`` category of your system’s applications list/start menu.
-- The other is accessed via the ``DZGUI`` desktop icon (Steam Deck only)
 
 From Steam
 --------------
-See :doc:`steam`.
+DZGUI will also ask you if you want to add a "non-Steam game" shortcut to Steam.
+This shortcut will launch DZGUI directly and comes with integrated grid and cover artwork.
+
+You must restart Steam for this shortcut to take effect in your library.
+
+.. note::
+   You can also pass DZGUI launch parameter's to the Steam shortcut via Steam's right-click menu. See :doc:`flags`.
