+            If you modify the Metadata in the linux-yocto 
+            <filename>meta</filename> branch, you must not forget to update 
+            the 
+            <ulink url='&YOCTO_DOCS_REF_URL;#var-SRCREV'><filename>SRCREV</filename></ulink>
+            statements in the kernel's recipe.
+            In particular, you need to update the 
+            <filename>SRCREV_meta</filename> variable to match the commit in 
+            the <filename>KMETA</filename> branch you wish to use.
+            Changing the data in these branches and not updating the 
+            <filename>SRCREV</filename> statements to match will cause the 
+            build to fetch an older commit.
