 ## Building
 
-Windows and Linux binaries are available for each [release](https://github.com/keharriso/love-nuklear/releases).
+Windows binaries are available for each [release](https://github.com/keharriso/love-nuklear/releases).
 
 To build the library yourself, grab the code with:
 ```sh
-$ git clone --recursive git@github.com:keharriso/love-nuklear.git
+$ git clone --recursive https://github.com/keharriso/love-nuklear.git
 ```
 
-Compile with CMake (I recommend using the MinGW generator on Windows). You'll need to tell CMake where to find the LuaJIT headers and binaries. The end result is a native Lua module.
+Next, you need to compile the code to a native Lua module.
+
+### Compiling with CMake on Linux
+
+1. First, ensure you have a C compiler and the `cmake` and `luajit` or `lua51-luajit` (for openSUSE) packages installed, as well as `libluajit-5.1-dev` (for Ubuntu/Debian), `luajit-devel` (for Fedora), or `lua51-luajit-devel` (for openSUSE) if your distro has one of these packages.
+2. Create a new folder next to `love-nuklear` called `love-nuklear-build`.
+3. Open a terminal inside `love-nuklear-build`.
+4. Compile the library with
+```sh
+$ cmake -DCMAKE_BUILD_TYPE=Release ../love-nuklear
+$ make
+```
+5. Locate `nuklear.so` in the build folder.
+
+#### Via GNU Guix
+
+LÖVE-Nuklear is also available as a [Guix](http://guix.gnu.org/) package, and can thus be directly downloaded and built via:
+```
+$ guix package --install love-nuklear
+```
+
+### Compiling with CMake and MinGW on Windows
+
+1. Install [CMake](https://cmake.org/download/) and [MinGW](http://mingw.org/) or [MinGW-w64](https://mingw-w64.org/doku.php).
+2. Download the source code for [LuaJIT](http://luajit.org/download.html).
+3. Open a command window inside the LuaJIT folder (the one that contains "README").
+4. Compile LuaJIT with
+```sh
+$ mingw32-make
+```
+5. Remember the path to `lua51.dll` inside the LuaJIT `src` folder.
+6. Run the CMake GUI.
+7. Click "Browse Source" at the top right, then select the `love-nuklear` folder.
+8. Enter a path for the build folder. It should be separate from the source folder.
+9. Press "Configure" at the bottom.
+10. Select "MinGW Makefiles" from the generator drop list, then click "Finish".
+11. You should receive an error. This is normal.
+12. Open the LUA tree by clicking the triangle on the left.
+13. Replace "LUA_INCLUDE_DIR-NOTFOUND" with the path to the LuaJIT `src` folder.
+14. Replace "LUA_LIBRARY-NOTFOUND" with the path to `lua51.dll` inside the LuaJIT `src` folder.
+15. Click "Generate" at the bottom.
+16. Open a command window inside the build folder.
+17. Compile with
+```sh
+$ mingw32-make
+```
+18. Locate `nuklear.dll` inside the build folder.
+
+### Compiling with CMake and MSVC on Windows
+
+1. Install [CMake](https://cmake.org/download/) and [Visual Studio](https://visualstudio.microsoft.com/).
+Community or Express edition is sufficient.
+2. Download the source code for [LuaJIT](http://luajit.org/download.html).
+3. Open a Visual Studio Command Prompt (x86 or x64 depending on what architecture you need)
+and set the current directory to the LuaJIT folder (the one that contains "README"). Also
+remember this path.
+4. At the VS Command Prompt, set your current directory to `src` then
+execute `msvcbuild.bat`. This will create lua51.dll, lua51.lib, and luajit.exe
+5. Now open new command prompt window inside the `love-nuklear` folder.
+6. Type `set "LUA_DIR=<path to directory at step 3>"`
+7. Then type `cmake -Bbuild -H. -A Win32 -DLUA_INCLUDE_DIR=%LUA_DIR%\src -DLUA_LIBRARY=%LUA_DIR%\src\lua51.lib -DCMAKE_INSTALL_PREFIX=%CD%\install`.
+If you previously compile LuaJIT using x64 VS command prompt, replace `Win32` with `x64` at above command.
+8. Then type `cmake --build build --config Release --target install` and you'll found `nuklear.dll` inside "install" folder.
