 This is a port of Linux 2.4 to Axis Communications ETRAX 100LX embedded 
 network CPU. For more information about CRIS and ETRAX please see further
 below.
 
-<to come: instructions on how to grab the right gcc, compiling and booting>
+In order to compile this you need a version of gcc with support for the
+ETRAX chip family. Please see this link for more information on how to 
+download the compiler and other tools useful when building and booting
+software for the ETRAX platform:

- * If you select CONFIG_KGDB in the configuration, the kernel will be built

+ * built with different gcc flags: "-g" is added to get debug infos, and
  * "-fomit-frame-pointer" is omitted to make debugging easier. Since the
  * resulting kernel will be quite big (approx. > 7 MB), it will be stripped
  * before compresion. Such a kernel will behave just as usually, except if
