 To build YAFFS in the Linux kernel tree you need to run the patch-ker.sh
-script, giving the path to your kernel sources, e.g:
+script from the yaffs soiurce directory, giving your chouce as to whether
+you wish to copy or link the code and the path to your kernel sources, e.g:
 
-./patch-ker.sh /usr/src/linux
+./patch-ker.sh c /usr/src/linux
 
 This will copy the yaffs files into fs/yaffs2 and modify the Kconfig
 and Makefiles in the fs directory.
 
+./patch-ker.sh l /usr/src/linux
+
+This does the same as the above but makes symbolic links instead.
+
 After you've run the script, go back to your normal kernel making procedure
 and configure the yaffs settings you want.
