+=========================================
 
+ 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
+		./build_init.sh
+	2. Cross compile entire userland software
+		./build_world.sh
+	3. Cross compile ELWIX kernel
+		./build_kernel.sh
+
+ III. Information
