+=========================================
 
+ 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>"
+ - We must checkout from ELWIX CVS repository core libraries "libait*" , "embedtools", "embedaddons" 
+and GPLv2 "gpl/*" projects
+ - Optional download of 3th party software for ELWIX firmware. Project name is embedaddon from ELWIX CVS
+
+ II. Build process
+ 	1. Init build structures with clean directory tree
+		./build_init.sh <filename of project config>
+	2. Cross compile entire userland software
+		./build_world.sh
+	3. Cross compile ELWIX kernel
+		./build_kernel.sh
+	4. Cross compile ELWIX tools
+		./build_tools.sh
+	5. Cross compile optional 3th party software 
+		./build_3thparty.sh
+	6. Now is moment for build base elwix system
+		./build_base.sh
+	7. Now moment comes to build big system binary and rootfs to embed into the kernel
+		./build_rootfs.sh
+	8. Make romfs image and build big fat second stage firmware image
+		./build_romfs.sh
+	9. Prepare fs image and populate /etc,/boot and others
+		./build_fs.sh
+
+ Ok, now we did ELWIX version and placed to build/release directory like tar.gz file
+
