  The first thing to install is [MSYS2](https://www.msys2.org) to provide a
  basic UNIX-like environment for Windows. Unfortunately, the binaries are not
  signed, so make sure you download it via HTTPS. However, packages you
  download and install via MSYS2 are cryptographically signed.

<h3 id="setting-up-msys2">Setting up MSYS2</h3>

  MSYS2 currently supports 7 different
  [environments](https://www.msys2.org/docs/environments/). All of them except
  for the one called just "MSYS" are supported, but which packages you need to
  install depends on the environment(s) you want to use. If you only want to
  target Windows 10 and newer, the CLANG64 and CLANG32 environments are the

  recommended ones.






  For CLANG64, use:

    $ pacman -Syu mingw-w64-clang-x86_64-clang mingw-w64-clang-x86_64-fossil

  For CLANG32, use:

    $ pacman -Syu mingw-w64-clang-i686-clang mingw-w64-clang-i686-fossil

  For CLANGARM64, use (you need to use Fossil via another environment):

    $ pacman -Syu mingw-w64-clang-aarch64-clang

  For MINGW64, use:

    $ pacman -Syu mingw-w64-x86_64-clang mingw-w64-x86_64-fossil

  For MINGW32, use:

    $ pacman -Syu mingw-w64-i686-clang mingw-w64-i686-fossil

  For UCRT64, use:

    $ pacman -Syu mingw-w64-ucrt-x86_64-clang mingw-w64-ucrt-x86_64-fossil

  When using `pacman` to install the packages, `pacman` might tell you to close
  the window. If it does so, close the window, restart MSYS2 and execute the
  `pacman` command again.

  There is nothing wrong with installing multiple environments, as MSYS2 has
  created shortcuts for each of them in your start menu. Just make sure to use
  the correct shortcut for the environment you want to use.
