+<h1>Introduction</h1>
+
+<p>FreeGLUT can initialize an OpenGL ES (GLES) context.  It works under platforms that supports EGL:</p>
+<ul>
+  <li>Android (see <a href="android.php">dedicated page</a>)</li>
+  <li>Unix X11 with Mesa EGL</li>
+</ul>
+
+<p>FreeGLUT ES is provided as a separate library, because OpenGL ES has a distinct,
+incompatible library for each version (e.g. -lGLESv1_CM and -lGLESv2).</p>
+
+<p>The following explains how to use FreeGLUT ES under Mesa EGL.</p>
+
+<a name="compiling"></a>
+<h1>Compiling</h1>
+
+<p>Here's how to compile FreeGLUT for GLES2:</p>
+
+<pre>
+cd /usr/src/freeglut-3.0.0/
+mkdir native-gles2/ && cd native-gles2/
+cmake \
+  -DCMAKE_INSTALL_PREFIX=/tmp/freeglut-native-gles2 \
+  -DFREEGLUT_GLES2=ON \
+  -DFREEGLUT_BUILD_DEMOS=NO \
+  ..
+make
+make install
+</pre>
+
+<a name="using"></a>
+<h1>Using in your projects</h1>
+
+<p>Get the 'freeglut-gles2' module through pkg-config.</p>
+
+<p>If you use CMake, you can do that with:</p>
+
+<pre>
+include(FindPkgConfig)
+pkg_check_modules(freeglut REQUIRED freeglut-gles2>=3.0.0)
+if(freeglut_FOUND)
+  include_directories(${freeglut_STATIC_INCLUDE_DIRS})
+  link_directories(${freeglut_STATIC_LIBRARY_DIRS})
+  set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${freeglut_STATIC_CFLAGS_OTHER}")
+  add_definitions(${freeglut_STATIC_CFLAGS_OTHER})
+endif()
+</pre>
+
+<pre>
+cd your_project/
+mkdir native-gles2/ && cd native-gles2/
+PKG_CONFIG_PATH=/tmp/freeglut-native-gles2/share/pkgconfig/ cmake ..
+</pre>
