 # Building from Source
-See the section for your platform on our wiki page [Compiling form Source](https://github.com/diasurgical/devilutionX/wiki/Compiling-from-Source)
+## 32-bit building on 64-bit platforms
+<details><summary>Linux</summary>
+
+### Installing dependencies on Debian and Ubuntu
+```
+sudo apt-get install cmake g++-multilib libsdl2-dev:i386 libsdl2-mixer-dev:i386 libsdl2-ttf-dev:i386 libsodium-dev libsodium-dev:i386
+```
+### Compiling
+```
+mkdir build
+cd build
+linux32 cmake -DCMAKE_TOOLCHAIN_FILE=../CMake/32bit.cmake ..
+linux32 make -j$(nproc)
+```
+</details>
+<details><summary>macOS</summary>
+
+### Installing dependencies
+Install [Xcode 9.4.1 and Xcode Command Line tools](https://developer.apple.com/download/more/?=xcode%209.4.1), this is the last version with **32 bits** support.
+
+Note: Be sure that your to select the command line Xcode if you have more then one installed:
+```
+$ sudo xcode-select --switch /Applications/Xcode.app
+```
+Install the build tools using [Homebrew](https://brew.sh/):
+```
+brew install automake autoconf libtool
+```
+Get SDL2, SDL2_mixer, SDL2_ttf and Libsodium:
+```
+./xcode-build.sh --get-libs
+```
+### Compiling
+```
+./xcode-build.sh --build-libs
+./xcode-build.sh --build-project
+./xcode-build.sh --package
+```
+</details>
+<details><summary>Windows via MinGW</summary>
+
+### Installing dependencies on Debian and Ubuntu
+
+Download and place the 32bit MinGW Development Libraries of [SDL2](https://www.libsdl.org/download-2.0.php), [SDL2_mixer](https://www.libsdl.org/projects/SDL_mixer/), [SDL2_ttf](https://www.libsdl.org/projects/SDL_ttf/) and [Libsodium](https://github.com/jedisct1/libsodium/releases) in `/user/i686-w64-mingw32`.
+
+```
+sudo apt-get install cmake gcc-mingw-w64-i686 g++-mingw-w64-i686
+```
+### Compiling
+```
+mkdir build
+cd build
+cmake -DASAN=OFF -DCMAKE_TOOLCHAIN_FILE=../CMake/mingwcc.cmake ..
+make -j$(nproc)
+```
+</details>
+
+## Building for the native platform
+*Note: Since 64-bit builds are currently not in a playable state, it is advised to build in a 32-bit environment. Another possibility is a 32-bit build on a 64-bit system (see above).*

+## CMake arguments
+### General
+The default build type is `Debug`. This can be changed with `-DBINARY_RELEASE=ON`. Independently of this, the debug mode of the Diablo engine is always enabled by default. It can be disabled with `-DDEBUG=OFF`. Finally, in debug builds the address sanitizer is enabled by default. This can be disabled with `-DASAN=OFF`.
+### mingw32
+Use `-DCROSS_PREFIX=/path/to/prefix` if the `i686-w64-mingw32` directory is not in `/usr`.
