+# Building Setup
+
+##### G3D is super delicate, meaning that you have to go about building in a special way
+
+#### Skip to steps 7-13 if you have already built this program
+
+1. Install Visual Studio 2005. Google where to find it. Make note of which version you downloaded.
+
+2. Download and install G3D from [this link here](https://sourceforge.net/projects/g3d/files/g3d-cpp/6.10/g3d-6_10_win32.exe/download).
+
+3. Make sure G3D is included under your build directories by going under Tools -> Options -> Projects and Solutions -> VC++ Directories and check and see if:
+
+* `g3d-6_10\bin` is under executable files
+
+* `g3d-6_10\include` is under include files
+
+* `g3d-6_10\bin` is under executable files
+
+* `g3d-6_10\win32-vc8-lib` is under library files
+
+* Ex: `C:\libraries\g3d-6_10\bin`
+
+4. Download SDL version 1.2.7 from [this link](http://www.libsdl.org/release/SDL-devel-1.2.7-VC6.zip)
+
+5. Extract the file to a folder on your computer. Keep note of this folder.
+
+6. Include the extracted files by going to Tools -> Options -> Projects and Solutions -> VC++ Directories and adding the following links:
+
+* Include files - extractpath\`include`
+
+* Library files - extractpath\`lib`
+
+* Ex: `C:\libraries\SDL-1.2.7\bin`
+
+#### Steps 7-11 are optional if you are using Visual Studio Professional. Check the Error stuff section if it doesn't work, most reference steps from here.
+
+7. Download and install the [platform SDK](https://www.microsoft.com/en-us/download/details.aspx?id=6510).
+
+8. Put the platform SDK into your directories (Tools -> Options -> Projects and Solutions -> VC++ Directories) by replacing all mentions of $(VCInstallDir)PlatformSDK with the actual path. 
+Ex: `$(VCInstallDir)PlatformSDK\include` -> `C:\Program Files\Microsoft Platform SDK\Include`
+
+9. Right click Source files -> Dialogs.rc -> View Code
+
+10. Edit line 10 to say
+```cpp
+#include "WinResrc.h"
+#define IDC_STATIC  -1
+```
+
+instead of
+
+```cpp
+#include "afxres.h"
+```
+
+11. Right click the project -> Properties -> Configuration Properties -> Linker -> Input, and add `AdvAPI32.lib` under Additional Dependencies. 
+
+### Continue back here if you're skipping steps 7-11
+
+12. Right click the project -> Properties -> Configuration Properties -> Linker -> General, and make sure Additional Library Directories is blank.
+
+13. Try building using Build -> Build G3DTest.
+
+
+## Error stuff
+
+```c:\libraries\g3d-6_10\include\G3D/platform.h(235) : fatal error C1083: Cannot open include file: 'windows.h': No such file or directory``` > Download and install platform SDK (lines 7-8)
