+notes on raylib 1.2
+-------------------
+
+On September 2014, after 5 month of raylib 1.1 release, it comes raylib 1.2. Again, this version presents a
+complete internal redesign of [core] (https://github.com/raysan5/raylib/blob/master/src/core.h) module to support two new platforms: Android and Raspberry Pi.
+
+It's been some month of really hard work to accomodate raylib to those new platforms while keeping it easy for the user.
+On Android, raylib manages internally the activity cicle, as well as the inputs; on Raspberry Pi, a complete raw input
+system has been written from scratch.
+
+A new display initialization system has been created to accomodate to multiple resolutions, adding black bars if required;
+user only defines whatever screen size and it gets properly displayed.
+
+Now raylib can easily deploy games to Android devices and Raspberry Pi (console mode).
+
+Lots of code changes and lot of testing have concluded in this amazing new raylib 1.2.

-building
---------
+building source (generate libraylib.a)
+--------------------------------------
+
+Building raylib sources on desktop platforms:
+
+Step 1: Using MinGW make tool, just navigate from command line to raylib/src/ folder and type:
+
+    mingw32-make PLATFORM=PLATFORM_DESKTOP
+
+* NOTE: By default raylib compiles using OpenGL 1.1 to maximize compatibility; to use OpenGL 3.3 just type:
+
+    mingw32-make PLATFORM=PLATFORM_DESKTOP GRAPHICS=GRAPHICS_API_OPENGL_33
+
+Building raylib sources 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/src/ folder and type:
+
+    make
+
+Building raylib sources for Android:
+
+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. 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 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:
 
-raylib could be build with the following command lines (Using GCC compiler):
-
-	cd raylib/src
-	gcc -c core.c -std=c99 -Wall
-	gcc -c shapes.c -std=c99 -Wall
-	gcc -c textures.c -std=c99 -Wall
-	gcc -c text.c -std=c99 -Wall

-    
-	ar rcs libraylib.a core.o shapes.o textures.o stb_image.o text.o models.o raymath.o rlgl.o utils.o stb_vorbis.o audio.o

+    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:

+
+    %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):
+
