+Miscellaneous Notes
+====================
+
+Video and Music Samples
+-----------------------
+This BSP includes recipes to download Ogg format video and
+music files that can be played-back with the Video and music players
+included in the sato images.  The sample files are installed in
+/home/Music and /home/Videos directories.  
+
+
+Adding Glxgears to image
+-------------------------
+Glxgears can be added to the generated image by adding "debug-tweaks"
+option to the extra image features variable in the default local.conf
+before building the BSP.
+
+e.g. to add Glxgears, locate the following line in local.conf
+EXTRA_IMAGE_FEATURES = "debug-tweaks"
+
+and change above line to..
+
+EXTRA_IMAGE_FEATURES = "debug-tweaks tools-testapps"
