+This git module contains template code for possible GStreamer projects.
+
+gst-app
+	basic autotools layout for writing a GStreamer-based application.
+
+gst-plugin
+	basic autotools layout and basic filter code for writing a
+	GStreamer plug-in.
+
+This code is provided under a MIT license [1], which basically means "do
+with it as you wish, but don't blame us if it doesn't work". You can use
+this code for any project as you wish, under any license as you wish. We
+recommend the use of the LGPL [2] license for applications and plugins,
+given the minefield of patents the multimedia is nowadays. See our website
+for details [3].
+
+Build each module like this:
+
+    cd gst-plugin
+    ./autogen.sh
+    make
+
+Modify gst-plugin/src/Makefile.am to add or remove source files to build or
+add additional dependencies or compiler flags or change the name of the
+plugin file to be installed. Run ./autoregen.sh if changes don't take effect
+automatically on 'make'.
+
+Modify gst-plugin/configure.ac to check for additional library dependencies
+or other features needed by your plugin. Run ./autoregen.sh if changes don't
+take effect automatically on 'make'.
+
+Once the plugin is built you can either install it with 'sudo make install'
+(however, this will by default go into the /usr/local prefix where it won't
+be picked up by a GStreamer installed from packages, so you would need to
+set the GST_PLUGIN_PATH environment variable to include or point to
+/usr/local/lib/gstreamer-1.0/ for your plugin to be found by a from-package
+GStreamer). Alternatively, you will find your plugin binary in
+gst-plugins/src/.libs/ as libgstplugin.so or similar (the extension may vary),
+so you can also set the GST_PLUGIN_PATH environmen variable to the
+gst-plugins/src/.libs/ directory (best to specify an absolute path though).
+
+You can also check if it has been built correctly with:
+
+    gst-inspect-1.0 gst-plugins/src/.libs/libgstplugin.so
