                     With additional layers, it is possible to use a pre-compiled
                     external toolchain.
                     One example is the Sourcery G++ Toolchain.
                     The support for this toolchain resides in the separate
+                    <trademark class='registered'>Mentor Graphics</trademark>
                     <filename>meta-sourcery</filename> layer at
                     <ulink url='http://github.com/MentorEmbedded/meta-sourcery/'></ulink>.
-                    You can use <filename>meta-sourcery</filename> as a
-                    template for adding support for other external toolchains.

-                    The <filename>TCMODE</filename> variable points the build
-                    system to a file in
-                    <filename>conf/distro/include/tcmode-${TCMODE}.inc</filename>.
-                    Thus, for <filename>meta-sourcery</filename>,
-                    which has <filename>conf/distro/include/tcmode-external-sourcery.inc</filename>,
-                    you would set the variable as follows:
-                    <literallayout class='monospaced'>
-     TCMODE ?= "external-sourcery"
-                    </literallayout>
+                    The layer's <filename>README</filename> file contains
+                    information on how to use the Sourcery G++ Toolchain as
+                    an external toolchain.
+                    In summary, you must be sure to add the layer to your
+                    <filename>bblayers.conf</filename> file in front of the
+                    <filename>meta</filename> layer and then set the
+                    <link linkend='var-EXTERNAL_TOOLCHAIN'><filename>EXTERNAL_TOOLCHAIN</filename></link>
+                    variable in your <filename>local.conf</filename> file
+                    to the location in which you installed the toolchain.
