+#### CMake / Win32 / MinGW Quickstart
+
+1. Install [MSYS2](https://www.msys2.org/) and start your preferred environment (ucrt64.exe is suggested and used in this example)
+2. Install the required libraries
+
+```shell
+pacman -S mingw-w64-ucrt-x86_64-gcc
+pacman -S mingw-w64-ucrt-x86_64-libmicrohttpd
+pacman -S mingw-w64-ucrt-x86_64-curl
+pacman -S mingw-w64-ucrt-x86_64-jansson
+```
+
+3. Build and install orcania into your MSYS environment:
+
+```shell
+git clone https://github.com/babelouest/orcania.git
+cmake -G Ninja -DCMAKE_C_COMPILER=C:/msys64/ucrt64/bin/gcc.exe -DCMAKE_CXX_COMPILER=C:/msys64/ucrt64/bin/g++.exe -DBUILD_STATIC=ON -DBUILD_BASE64URL=OFF -DCMAKE_INSTALL_PREFIX=C:/msys64/ucrt64/ -B ./orcania/build orcania
+cmake --build ./orcania/build
+cmake --install ./orcania/build
+```
+
+4. Build and install yder into your MSYS environment:
+
+```shell
+git clone https://github.com/babelouest/yder.git
+cmake -G Ninja -DCMAKE_C_COMPILER=C:/msys64/ucrt64/bin/gcc.exe -DCMAKE_CXX_COMPILER=C:/msys64/ucrt64/bin/g++.exe -DBUILD_STATIC=ON -DCMAKE_INSTALL_PREFIX=C:/msys64/ucrt64/ -B ./yder/build yder
+cmake --build ./yder/build
+cmake --install ./yder/build
+```
+
+5.  Add ulfius to your application CMakeLists.txt, make sure to replace YOUR_ULFIUS_SRC_PATH
+
+```CMake
+# Adjust these and other option flags as you desire
+option(BUILD_STATIC "..." ON)
+option(BUILD_SHARED "..." OFF)
+option(WITH_YDER "..." OFF)
+option(BUILD_UWSC "..." OFF)
+set(MHD_LIBRARY "C:/msys64/ucrt64/lib/libmicrohttpd.a")
+set(MHD_INCLUDE_DIR "C:/msys64/ucrt64/include")
+add_subdirectory(YOUR_ULFIUS_SRC_PATH ulfius)
+
+target_link_libraries(app PRIVATE ulfius_static)
