 This sequence does *not* install the dependencies from submodules; instead they must be installed in the usual places on the build system, otherwise the `./configure` step below will fail.

+## Seedtool on Windows
+
+### Abstract
+
+This document describes building `seedtool` with `MSYS2` and its usage on `Windows 10` 64-bit.
+
+### Installing MSYS2 and Packages
+
+* First, install `MSYS2` by downloading the installer and following the installation guide in [www.msys2.org](www.msys2.org).
+
+* Run `MSYS2` and make sure the package database is updated:
+
+```bash
+# pacman -Syu
+# pacman -Su
+```
+
+* Next, install the compiler and the required packages:
+
+```bash
+# pacman -S mingw-w64-x86_64-clang
+# pacman -S patch
+# pacman -S git
+# pacman -S make
+# pacman -S mingw-w64-x86_64-libc++
+# pacman -S autoconf
+# pacman -S automake1.8
+```
+
+### Compiling
+
+First, clone `bc-seedtool-cli`, e.g. into `C:\msys64\home`, open `MSYS2 MinGW 64-bit` application and `cd` into `C:\msys64\home\bc-seedtool-cli`
+
+* Now, run the build script with:
+
+```bash
+# export CC="clang" && export CXX="clang++" && ./build.sh
+```
+
+* and install:
+
+```bash
+# make install
+```
+
+You can now freely use `seedtool` inside `MSYS2 MinGW 64-bit` console.
+
+
+### Running Seedtool as a Native Windows App
+
+To be able to use `seedtool` as a native app on Windows outside `msys2/mingw64`, you have to expose 3 files to the system: `seedtool.exe`, `libc++.dll` and `libunwind.dll` which all reside in `C:\msys64\mingw64\bin`. So go ahead and add that folder to the `Windows PATH` by the following command in `Windows Cmd`:
+
+```bash
+set PATH=%PATH%;C:\msys64\mingw64\bin
+```
+
+That's it. Now you can use `seedtool` as a native Windows app in the Windows command line tool.
+
+
+*Note:* If you want to pipe seedtool ouput into a QR code generator, you could use:
+
+```bash
+seedtool --ur | python -c "import sys; print(sys.stdin.readlines()[0].upper())" | qr > seedqrcode.png
+```
+
+For this you'll need `Python` and the following package:
+
+```bash
+pip install qrcode[pil]
+```
+
