+# Compiling
+
+OpenMoHAA supports any architecture, thanks to the CMake build system and cross-platform code/libraries. While the most common little-Endian architectures (arm, aarch64, x86, x86_64) have been tested and confirmed to work, big-Endian architectures should be supported as well; however, they remain untested.
+
+The following tools are required for all platforms:
+- CMake >= 3.5
+- Flex (>= 2.6.4) and Bison (>= 3.5.1)
+- A C++11 compiler is also required.
+
+The installation directory can be set to the MOHAA directory.
+
+By default, the build will produce both the client and dedicated server versions. The client can be omitted from the build by appending `-DBUILD_NO_CLIENT=1` to the CMake command-line arguments. Using this parameter will result in only the server portion being built.
+
+## Compiling for Linux
+
+These are the tools required on Linux :
+- Clang >= 3.3 or GCC >= 4.8.5
+- libsdl2-dev
+
+**clang-3.5** and **gcc-4.8.5** should work (tested on Ubuntu 16.04), but the latest version should be used.
+
+Ubuntu 20.04 is the minimum version required to fully compile the project successfully.
+
+1 line install command with clang:
+```sh
+sudo apt-get install -y cmake ninja-build clang lld flex bison libsdl2-dev
+```
+
+Example with **CMake** and **ninja-build** installed:
+```sh
+mkdir .cmake && cd .cmake
+cmake -G Ninja ../
+```
+
+Other compilers can be specified by appending `-DCMAKE_C_COMPILER=/path/to/compiler -DCMAKE_CXX_COMPILER=path/to/compiler` to the CMake command-line.
+
+## Compiling for Windows
+
+Visual Studio (2019 or 2022) is generally preferred.
+
+Flex and Bison can be downloaded from here: https://github.com/lexxmark/winflexbison/releases/tag/v2.5.25
+
+Append `-DFLEX_EXECUTABLE=...\win_flex.exe -DBISON_EXECUTABLE=...\win_bison.exe` to the CMake command-line to use the package from the link above.
