-Install Requirements and Dependencies
-*************************************
-
-.. NOTE FOR DOCS AUTHORS: DO NOT PUT DOCUMENTATION BUILD DEPENDENCIES HERE.
-
-   This section is for dependencies to build Zephyr binaries, *NOT* this
-   documentation. If you need to add a dependency only required for building
-   the docs, add it to doc/README.rst. (This change was made following the
-   introduction of LaTeX->PDF support for the docs, as the texlive footprint is
-   massive and not needed by users not building PDF documentation.)
-
-There are 2 different ways of developing for Zephyr on Microsoft Windows:
-
-#. :ref:`windows_install_native` (recommended)
-#. :ref:`windows_install_wsl`
-
-The first option is fully Windows native; the other requires emulation layers
-that may result in slower build times.

-
-Option 1: Windows Command Prompt
-================================
-
-These instructions assume you are using the ``cmd.exe`` command prompt. Some of
-the details, such as setting environment variables, may differ if you are using
-PowerShell.
-
-The easiest way to install the native Windows dependencies is to first install
-`Chocolatey`_, a package manager for Windows.  If you prefer to install
-dependencies manually, you can also download the required programs from their
-respective websites.
-
-.. note::
-   Chocolatey will properly set up your environment so tools can be
-   found on your PATH.  If you install programs manually, be sure to
-   verify the programs can also be found on your PATH.  For example,
-   you may need to add ``C:\\Program Files\Git\bin`` after manually
-   installing Git for Windows.
-
-.. note::
-   There are multiple ``set`` statements in this tutorial. You can avoid
-   typing them every time by placing them inside a ``.cmd`` file and
-   running that every time you open a command prompt.
-
-#. If you're behind a corporate firewall, you'll likely need to specify a
-   proxy to get access to internet resources:
-
-   .. code-block:: console
-
-      set HTTP_PROXY=http://user:[email protected]:1234
-      set HTTPS_PROXY=http://user:[email protected]:1234
-
-#. Install :program:`Chocolatey` by following the instructions on the
-   `Chocolatey install`_ page.
-
-#. Open a command prompt (``cmd.exe``) as an **Administrator** (press the
-   Windows key, type "cmd.exe" in the prompt, then right-click the result and
-   choose "Run as Administrator").
-
-#. Optionally disable global confirmation to avoid having to confirm
-   installation of individual programs:
-
-   .. code-block:: console
-
-      choco feature enable -n allowGlobalConfirmation
-
-#. Install CMake:
-
-   .. code-block:: console
-
-      choco install cmake --installargs 'ADD_CMAKE_TO_PATH=System'
-
-#. Install the rest of the tools:
-
-   .. code-block:: console
-
-      choco install git python ninja dtc-msys2 gperf
-
-#. Close the Administrator command prompt window.
