 Stefan Weil provides binaries and installers for
 both [32-bit](https://qemu.weilnetz.de/w32/) and
 [64-bit](https://qemu.weilnetz.de/w64/) Windows.
+
+**MSYS2:**
+
+QEMU can be installed using [MSYS2](https://www.msys2.org/) also. MSYS2 uses
+[pacman](https://wiki.archlinux.org/title/Pacman) to manage packages. First,
+follow the [MSYS2](https://www.msys2.org/) installation procedure. Then update
+the packages with `pacman -Syu` command. Now choose the proper command for your
+system as following:
+
+* For 32 bit Windows 7 or above (in MINGW32):
+
+```
+pacman -S mingw-w64-i686-qemu
+```
+
+* For 64 bit Windows 7 or above (in MINGW64):
+
+```
+pacman -S mingw-w64-x86_64-qemu
+```
+
+* For 64 bit Windows 8.1 or above (in UCRT64):
+
+```
+pacman -S mingw-w64-ucrt-x86_64-qemu
+```
+
+Some QEMU related tools can be found in separate packages. Please see the
+MSYS2's [mingw-w64-qemu](https://packages.msys2.org/base/mingw-w64-qemu) page
+for more information. Any QEMU package related issues can be found in
+[MINGW-packages](https://github.com/msys2/MINGW-packages/issues?q=is%3Aissue+is%3Aopen+qemu)
+repository.
