-# starfish-sdk-x86_64
-LG Gstreamer toolchain
+starfish-sdk-x86_64
+===================
+
+# Description
+
+This is the "starfish" toolchain that is being used by LG to compile their
+webOS based firmware for their range of smart TVs.
+
+This version, along with its sysroot dependencies, was obtained through a
+legal inquiry at https://opensource.lge.com/inquiry, and extracted from the
+`MR_firmware.zip` archive that can itself be found in the `webOS 5.0 JO 2.0`
+archive downloadable [here](http://opensource.lge.com/product/list?page=&ctgr=005&subCtgr=006&keyword=OLED65CX5LB).
+
+This should be the exact same toolchain as the one LG used to compile
+version `04.40.20` of their LG OLED##CX### smart TVs firmware.
+
