+notes on raylib 1.4
+-------------------
+
+On February 2016, after 4 months of raylib 1.3 release, it comes raylib 1.4. For this new version, 
+lots of parts of the library have been reviewed, lots of bugs have been solved and some interesting features have been added.
+
+First big addition is a set of [Image manipulation functions](https://github.com/raysan5/raylib/blob/develop/src/raylib.h#L673) have been added to crop, resize, colorize, flip, dither and even draw image-to-image or text-to-image.
+Now a basic image processing can be done before converting the image to texture for usage.
+
+SpriteFonts system has been improved, adding support for AngelCode fonts (.fnt) and TrueType Fonts (using [stb_truetype](https://github.com/nothings/stb/blob/master/stb_truetype.h) helper library). 
+Now raylib can read standard .fnt font data and also generate at loading a SpriteFont from a TTF file.
+
+New [physac](https://github.com/raysan5/raylib/blob/develop/src/physac.h) physics module for basic 2D physics support. Still in development but already functional. 
+Module comes with some usage examples for basic jump and level interaction and also force-based physic movements.
+
+[raymath](https://github.com/raysan5/raylib/blob/develop/src/raymath.h) module has been reviewed; some bugs have been solved and the module has been converted to a header-only file for easier portability, optionally, functions can also be used as inline. 
+
+[gestures](https://github.com/raysan5/raylib/blob/develop/src/gestures.c) module has redesigned and simplified, now it can process touch events from any source, including mouse. 
+This way, gestures system can be used on any platform providing an unified way to work with inputs and allowing the user to create multiplatform games with only one source code.
+
+Raspberry Pi input system has been redesigned to better read raw inputs using generic Linux event handlers (keyboard:`stdin`, mouse:`/dev/input/mouse0`, gamepad:`/dev/input/js0`). 
+Gamepad support has also been added (experimental).
+
+Other important improvements are the functional raycast system for 3D picking, including some ray collision-detection functions, 
+and the addition of two simple functions for persistent data storage. Now raylib user can save and load game data in a file (only some platforms supported). 
+A simple [easings](https://github.com/raysan5/raylib/blob/develop/src/easings.h) module has also been added for values animation.
+
+Up to 8 new code examples have been added to show the new raylib features and +10 complete game samples have been provided to learn 
+how to create some classic games like Arkanoid, Asteroids, Missile Commander, Snake or Tetris.
+
+Lots of code changes and lots of hours of hard work have concluded in this amazing new raylib 1.4.
+
+notes on raylib 1.5
+-------------------
+
+On July 2016, after 5 months of raylib 1.4 release, arrives raylib 1.5. This new version is the biggest boost of the library until now, lots of parts of the library have been redesigned, lots of bugs have been solved and some **AMAZING** new features have been added.
+
+VR support: raylib supports **Oculus Rift CV1**, one of the most anticipated VR devices in the market. Additionally, raylib supports simulated VR stereo rendering, independent of the VR device; it means, raylib can generate stereo renders with custom head-mounted-display device parameteres, that way, any VR device in the market can be **simulated in any platform** just configuring device parameters (and consequently, lens distortion). To enable VR is [extremely easy](https://github.com/raysan5/raylib/blob/develop/examples/core_oculus_rift.c).
+
+New materials system: now raylib supports standard material properties for 3D models, including diffuse-ambient-specular colors and diffuse-normal-specular textures. Just assign values to standard material and everything is processed internally.
+
+New lighting system: added support for up to 8 configurable lights and 3 light types: **point**, **directional** and **spot** lights. Just create a light, configure its parameters and raylib manages render internally for every 3d object using standard material.
+
+Complete gamepad support on Raspberry Pi: Gamepad system has been completely redesigned. Now multiple gamepads can be easily configured and used; gamepad data is read and processed in raw mode in a second thread.
+
+Redesigned physics module: [physac](https://github.com/raysan5/raylib/blob/develop/src/physac.h) module has been converted to header only and usage [has been simplified](https://github.com/raysan5/raylib/blob/develop/examples/physics_basic_rigidbody.c). Performance has also been singnificantly improved, now physic objects are managed internally in a second thread.
+
+Audio chiptunese support and mixing channels: Added support for module audio music (.xm, .mod) loading and playing. Multiple mixing channels are now also supported. All this features thanks to the amazing work of @kd7tck.
+
+Other additions include a [2D camera system](https://github.com/raysan5/raylib/blob/develop/examples/core_2d_camera.c), render textures for offline render (and most comprehensive [postprocessing](https://github.com/raysan5/raylib/blob/develop/examples/shaders_postprocessing.c)) or support for legacy OpenGL 2.1 on desktop platforms.
+
+This new version is so massive that is difficult to list all the improvements, most of raylib modules have been reviewed and [rlgl](https://github.com/raysan5/raylib/blob/develop/src/rlgl.c) module has been completely redesigned to accomodate to new material-lighting systems and stereo rendering. You can check [CHANGELOG](https://github.com/raysan5/raylib/blob/develop/CHANGELOG) file for a more detailed list of changes.
+
+Up to 8 new code examples have been added to show the new raylib features and also some samples to show the usage of [rlgl](https://github.com/raysan5/raylib/blob/develop/examples/rlgl_standalone.c) and [audio](https://github.com/raysan5/raylib/blob/develop/examples/audio_standalone.c) raylib modules as standalone libraries.
+
+Lots of code changes (+400 commits) and lots of hours of hard work have concluded in this amazing new raylib 1.5.

-_Step 2._ Create the following environment variables with the correct paths: 
-
-    ANDROID_SDK_TOOLS = C:\android-sdk\platform-tools
-    ANDROID_NDK_ROOT = C:\android-ndk-r10b
-    ANT_HOME = C:\apache-ant-1.9.4
-
-_Step 3._ Navigate from command line to folder `raylib/template_android/` and type:
-
-    %ANDROID_NDK_ROOT%\ndk-build
-
-NOTE: libraylib.a will be generated in folder `raylib/src_android/obj/local/armeabi/`, it must be copied
-to Android project; if using `raylib/template_android` project, copy it to `raylib/template_android/jni/libs/`.
-
-**Building raylib sources for Web (HTML5)**
-
-_Step 1._ Make sure you have installed emscripten SDK:
-
-> Download latest version from [here](http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html). I recommend downloading the [Portable Emscripten SDK for Windows](https://s3.amazonaws.com/mozilla-games/emscripten/releases/emsdk-1.25.0-portable-64bit.zip) and decompress it in `C:\emsdk-1.25.0` folder. After that, follow the portable version installation instructions.
-
-_Step 2._ Open `raylib/src/makefile` on Notepad++ and run the script named `raylib_makefile_emscripten`
+Check raylib wiki page: [Compile for...](https://github.com/raysan5/raylib/wiki)
 
 building examples
 -----------------
 
-**Building raylib examples on desktop platforms:**
-
-_Step 1:_ Using MinGW make tool, just navigate from command line to `raylib/examples/` folder and type:
-
-    mingw32-make PLATFORM=PLATFORM_DESKTOP
-
-NOTE: Make sure the following libs (and their headers) are placed on their respectibe MinGW folders:
-
-    libglfw3.a    - GLFW3 (static version)
-    libglew32.a   - GLEW, OpenGL extension loading, only required if using OpenGL 3.3+ or ES2
-    libopenal32.a - OpenAL Soft, audio device management
-
-**Building raylib examples on Raspberry Pi:**
-
-_Step 1._ Make sure you have installed in your Raspberry Pi OpenAL Soft library for audio:
-
-    sudo apt-get install openal1
-
-_Step 2._ Navigate from command line to `raylib/examples/` folder and type:
-
-    make
-
-**Building raylib examples for HTML5 (emscripten):**
-
-_Step 1._ Make sure you have installed emscripten SDK:
-
-> Download latest version from [here](http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html). I recommend downloading the [Portable Emscripten SDK for Windows](https://s3.amazonaws.com/mozilla-games/emscripten/releases/emsdk-1.25.0-portable-64bit.zip) and decompress it in `C:\emsdk-1.25.0` folder. After that, follow the portable version installation instructions.
-
-_Step 2._ Open `raylib/examples/makefile` on Notepad++ and run the script named `raylib_makefile_emscripten`
-
-NOTE: At this moment, raylib examples are not ready to directly compile for HTML5, code needs to be reorganized due to the way web browsers work. To see how code should be refactored to fit compilation for web, check [core_basic_window_web.c](https://github.com/raysan5/raylib/blob/master/examples/core_basic_window_web.c) example.
-
-**Building raylib project for Android (using template):**
-
-_Step 1._ Make sure you have installed Android SDK, Android NDK and Apache Ant tools:
-
-> Download and decompress on C: [Android SDK r23] (http://dl.google.com/android/android-sdk_r23.0.2-windows.zip)
-
-> Download and decompress on C: [Android NDK r10b] (http://dl.google.com/android/ndk/android-ndk32-r10b-windows-x86.zip)
-
-> Download and decompress on C: [Apache Ant 1.9.4] (http://ftp.cixug.es/apache//ant/binaries/apache-ant-1.9.4-bin.zip)
-
-_Step 2._ Create the following environment variables with the correct paths: 
-
-    ANDROID_SDK_TOOLS = C:\android-sdk\platform-tools
-    ANDROID_NDK_ROOT = C:\android-ndk-r10b
-    ANT_HOME = C:\apache-ant-1.9.4
-
-_Step 3._ To compile project, navigate from command line to folder `raylib/template_android/` and type:
-
-    %ANDROID_NDK_ROOT%\ndk-build
-
-_Step 4._ To generate APK, navigate to folder `raylib/template_android/` and type:
-
-    %ANT_HOME%\bin\ant debug
-
-_Step 5:_ To install APK into connected device (previously intalled drivers and activated USB debug mode on device):
-
-    %ANT_HOME%\bin\ant installd
-
-_Step 6:_ To view log output from device:
-
-    %ANDROID_SDK_TOOLS%\adb logcat -c
-    %ANDROID_SDK_TOOLS%\adb -d  logcat raylib:V *:S

+/*******************************************************************************************
+*
+*   raylib [rlgl] example - Oculus minimum sample
+*
+*   NOTE: This example requires OpenGL 3.3 or ES2 versions for shaders support,
+*         OpenGL 1.1 does not support shaders but it can also be used.
+*
+*   Compile rlgl module using:
+*   gcc -c rlgl.c -Wall -std=c99 -DRLGL_STANDALONE -DRAYMATH_IMPLEMENTATION -DGRAPHICS_API_OPENGL_33 -DRLGL_OCULUS_SUPPORT
+*
+*   NOTE 1: rlgl module requires the following header-only files:
+*       external/glad.h - OpenGL extensions loader (stripped to only required extensions)
+*       shader_standard.h - Standard shader for materials and lighting
+*       shader_distortion.h - Distortion shader for VR
+*       raymath.h - Vector and matrix math functions
+*
+*   NOTE 2: rlgl requires LibOVR (Oculus PC SDK) to support Oculus Rift CV1
+*
+*   Compile example using:
+*   gcc -o rlgl_oculus_rift.exe rlgl_oculus_rift.c rlgl.o -L. -lLibOVRRT32_1 -lglfw3 -lopengl32 -lgdi32 -std=c99
+*
+*   NOTE: Example must be linked against LibOVRRT32_1.dll that comes with Oculus Rift runtime.
+*
+*   This example has been created using raylib 1.5 (www.raylib.com)

+*
+*   raylib [rlgl] example - Using rlgl module as standalone module
+*
+*   NOTE: This example requires OpenGL 3.3 or ES2 versions for shaders support,
+*         OpenGL 1.1 does not support shaders but it can also be used.
+*
+*   Compile rlgl module using:
+*   gcc -c rlgl.c -Wall -std=c99 -DRLGL_STANDALONE -DRAYMATH_IMPLEMENTATION -DGRAPHICS_API_OPENGL_33
+*
+*   NOTE: rlgl module requires the following header-only files:
+*       external/glad.h - OpenGL extensions loader (stripped to only required extensions)
+*       shader_standard.h - Standard shader for materials and lighting
+*       shader_distortion.h - Distortion shader for VR
+*       raymath.h - Vector and matrix math functions
+*
+*   Compile example using:
+*   gcc -o rlgl_standalone.exe rlgl_standalone.c rlgl.o -lglfw3 -lopengl32 -lgdi32 -std=c99
+*
+*   This example has been created using raylib 1.5 (www.raylib.com)
