 There are several examples, including a media player, in the examples/
 directory, that demonstrate how to use the API and there are API docs in the
 docs/reference/html directory.  The core plug-ins, such as Gst::Identity and
-Gst::FileSrc are also provide along with many of the base plug-ins.
+Gst::FileSrc are also provided along with many of the base plug-ins.

+Dependencies
+============
 
 gstreamermm requires glibmm >= 2.16.0, giomm >= 2.16.0, and libxml++ >= 2.14.0
 along with the libraries that these require.  For the examples, gtkmm >= 2.12
 is also required.
 
+Build Dependencies
+==================
+
+To build gstreamermm from git (not from tarballs), many gstreamer plugins must 
+be available. If you also built gstreamer and gst-plugins-good from source then 
+you must have the correct libraries installed when building them.
+
+For instance on debian/Ubuntu, apt-get install:
+libvorbis-dev, libtheora-dev, libasound-dev, libxv-dev, libvisual-0.4-dev, libcdparanoia-dev
+
+You will also need to use --enable-experimental when building gst-plugins-base, to build the giosink plugin.
