 This document outlines the process of building bullet-jme on different platforms.
-Since bullet-jme is a native java library and bullet gets included statically,
+Since bulletjme is a native java library and bullet gets included statically,
 building requires you to download and build the bullet source first.
 
+Note that you do need to have CMake and a GCC compiler installed as well as
+the Android NDK in case you want to build for android too.
+
+-----------------------------------
+Requirements
+-----------------------------------
+ALL PLATFORMS
+- Java SDK 1.5+: http://java.sun.com
+- Apache ANT: http://ant.apache.org (Included in most Java IDEs)
+- Android NDK (optional): http://developer.android.com/sdk/ndk/index.html
+
+WINDOWS
+- Install mingw GNU C++ Compiler: http://www.mingw.org/
+- Install CMake: http://www.cmake.org/
+
+Mac OSX
+- Install XCode: http://developer.apple.com/ (or via the App Store)
+- Install http://www.macports.org
+- Install cmake via macports, in the Terminal type:
+> sudo port install cmake
+
+LINUX
+- Install cmake (and gcc if not available) via your package manager of choice, e.g.
+> sudo apt-get install cmake
+
+-----------------------------------
+Building
+-----------------------------------
+The build script in this directory does everything needed to download and compile
+bullet and the jme-bullet library, you only need to call the appropriate ant target,
+via your IDE or command line:
+
+> ant build-bullet-natives
+
+..and all of the steps below are executed automatically, including the download.
+
+You can alter options in the "nbproject/bullet.properties" file, such as the used
+bullet version, native compilation options (see below), path to Android NDK etc.
+
+-----------------------------------
+Altering the native build process
+-----------------------------------
+bullet-jme uses cpptasks to compile native code as well as the Android NDK.
+
+If you get compilation errors, try setting "native.java.include" in the build.properties file to your
+JDK include directory, e.g. /opt/java/include or "c:\Program Files\Java\jdk1.6.0_20\include".
+
+To change the used compiler, edit the "native.platform.compiler" entry in the
+"build.properties" file. The following c++ compilers work with cpptasks:
+
+gcc     GCC C++ compiler
+g++     GCC C++ compiler
+c++     GCC C++ compiler
+msvc    Microsoft Visual C++
+bcc     Borland C++ Compiler
+icl     Intel C++ compiler for Windows (IA-32)
+ecl     Intel C++ compiler for Windows (IA-64)
+icc     Intel C++ compiler for Linux (IA-32)
+ecc     Intel C++ compiler for Linux (IA-64)
+CC      Sun ONE C++ compiler
+aCC     HP aC++ C++ Compiler
+wcl     OpenWatcom C/C++ compiler
+
+In the "nbproject" folder you can find "build-native-platform.xml" files containing the commands
+to compile bullet-jme on different platforms. If you want to alter the process,
+you can copy and modify one of the files and import it in the "build.xml" file instead
+of the old one.
+
+-----------------------------------
+Netbeans Project
+-----------------------------------
+The project also includes a Netbeans project to edit and build
+the source in the Netbeans IDE in the /src/bullet/ subfolder.
+
+To have correct syntax highlighting in .cpp/.h files:
+
+- in Netbeans Settings -> C/C++ -> Code Assistance -> C++
+  - add bullet-2.77/src as include directories for c++
+  - add JAVA_HOME/include as include directories for c++
+
