 =========================================
 
  I. Intro
+ 	Before starting any work on ELWIX must we prepare environment.
 
- II. Build process
+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
 
- III. Information
+ II. Build system 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 BaseFS ELWIX system
+		./build_base.sh
+---------------------------------------------------------------------------------
+	7. Moment comes for build big system binary and inject rootfs image into kernel
+		./build_rootfs.sh
+	8. Make romfs image and build big fat second stage firmware image
+		./build_romfs.sh
+	9. Now is moment for build RootFS ELWIX system
+		./build_fs.sh
+---------------------------------------------------------------------------------
+
+ Ok, now we did ELWIX version and placed to build/release directory like tar.gz file
+
+ Example of produced tar balls::
+ 	ELWIX_X.X_target_{base|rootfs|rootfsext}_size_arch_date.tar.gz
+
+ III. Build storage image
+ 	1. Build ELWIX system into binary fs image file
+		./install2img <ELWIX_X.X_target_.....tar.gz> [image_size_in_KB]
+	2. Build ELWIX system into direct device
+		./install2dev </dev/daX> <ELWIX_X.X_target_.....tar.gz>
+	3. Build ELWIX system into separate compressed binary images for u-boot embedded devices
+		./install2uboot <kernel|kernel_rootfs|rootfs|bin|vendor>
+
+ IV. Emergency default address
+ 	IP: 10.254.254.254/30
+	VLAN: 4093
+
+	You should setup at your side 10.254.254.253/30 on VLAN 4093
