 =========================================
 
  I. Intro
+ 	Before starting any work on ELWIX must we prepare environment.
+
+What this means ::
+ - We must downloading freebsd sources from CVS/SVN repository and put on separate place from /usr/src.
+Set in config/rc.elwix variable BSDSRC="..." with place where you get freebsd sources.
+ - We gather from ELWIX CVS repository kodicom_mux project. After this we need to patch our freebsd
+sources like that "cd <where you put freebsd sources>; patch -p0 < <kodicom_mux/contrib/kodicom.patch>"
 
  II. Build process
  	1. Init build structures with clean directory tree
