+# libgui
+
+
+## Usage
+Following steps are required for initialization:
+```
+InitOSFunctionPointers();   // Load OS functions
+InitPadScoreFunctionPointers();
+InitVPadFunctionPointers(); // Input functions for GUI control
+InitFSFunctionPointers();   // To load file from the SD Card
+InitGX2FunctionPointers();  // For rendering
+InitAXFunctionPointers();   // For sound
+
+mount_sd_fat("sd");			// Mounting the SD Card
+memoryInitialize();			// Initialize memory management
+
+//DO GUI STUFF HERE!
+
+memoryRelease();
+unmount_sd_fat("sd");
+```
+
+Link the application with:
+```
+-lgui -lutils -ldynamiclibs -lfreetype -lgd -lpng -ljpeg -lz  -lmad -lvorbisidec
+```
+
+TODO: provide more information
+
+## Dependencies
+To be able to use libgui, you need to install the following dependencies:
+
+- Application needs to be loaded from the [homebrew_launcher](https://github.com/dimok789/homebrew_launcher)
+- [libutils](https://github.com/Maschell/libutils) for common functions.
+- [dynamic_libs](https://github.com/Maschell/dynamic_libs/tree/lib) for access to the functions.
+
+And other portable libraries that can be found in the "libs" folder of this repository. Extract the "portlibs.zip" into your devkitPro directory.
+This package includes:
+
+- freetype2 
+- libgd 
+- libpng 
+- libjpeg 
+- libz  
+- libmad 
+- vorbisidec
+
+# Credits
+- Orignally based on https://github.com/dborth/libwiigui
+- Wii U port / modification / new functions / sound / much more by dimok.
