  I. Intro
@@ -15,27 +15,56 @@ sources like that "cd <where you put freebsd sources>;
 and GPLv2 "gpl/*" projects
  - Optional download of 3th party software for ELWIX firmware. Project name is embedaddon from ELWIX CVS
 
- II. Build system process
+ II. Fresh FreeBSD source tree
+ 	1. When you get new FreeBSD source tree. You should apply patches
+		./apply_patches.sh
+
+ III. Build system process
  	1. Init build structures with clean directory tree
 		./build_init.sh <filename of project config>
+		Result after its work is cleaned previous storage and created new structure for build process
 	2. Cross compile entire userland software
 		./build_world.sh
+		Result from build_world.sh. Cross built whole FreeBSD project and 
+			prepared cross build scripts for ELWIX further build processes.
 	3. Cross compile ELWIX kernel
 		./build_kernel.sh
+		Result from ./build_kernel.sh. Cross built two kernels. One for ELWIX Base image without
+			embedded RootFS and another with RootFS for ELWIX RootFS images.
 	4. Cross compile ELWIX tools
 		./build_tools.sh
+		Result from ./build_tools.sh. Cross built ELWIX core tools, libraries and services.
+		Produced ELWIX system package file elwix-pkg.frm 
 	5. Cross compile optional 3th party software 
 		./build_3thparty.sh
+		Result from build_3thparty.sh. Cross built optional 3th party software for project.
+		Produced ELWIX system image file elwix-firmware2.sys
 ---------------------------------------------------------------------------------
 	6. Now is moment for build BaseFS ELWIX system
 		./build_base.sh
+		Result from build_base.sh. Built ELWIX Base OS version.
+		All software will be installed directly on flash/disk storage.
+		Script leave ready to install archive and compressed kernel.gz
+		Example for ready for install archive: ELWIX-2.6_x86_base_128mb_i386_2017-10-10.tar.gz
 ---------------------------------------------------------------------------------
 	7. Moment comes for build big system binary and inject rootfs image into kernel
 		./build_rootfs.sh
+		Result from build_rootfs.sh.
+		Cross built and leave image rootfs.img which was been injected into kernel.
+		Script prepared compressed kernel with embedded zero stage image of ELWIX into kernel_rootfs.gz
 	8. Make romfs image and build big fat second stage firmware image
 		./build_romfs.sh
+		Result from build_romfs.sh. Script collected files and prepare first stage ELWIX image.
+		Produced ELWIX system image file elwix-firmware.sys
 	9. Now is moment for build RootFS ELWIX system
 		./build_fs.sh
+		Result from build_fs.sh. Built ELWIX RootFS OS versions.
+		All software will be installed as images on flash/disk storage.
+		Script produced two version of ELWIX OS:
+			- RootFS small image which consume more RAM because all software is into memory drives.
+			Example for ready for install archive: ELWIX-2.6_x86_rootfs_64mb_i386_2017-10-10.tar.gz
+			- RootFS image which partially installed base tools directly onto flash.
+			Example for ready for install archive: ELWIX-2.6_x86_rootfsext_128mb_i386_2017-10-10.tar.gz

  Ok, now we did ELWIX version and placed to build/release directory like tar.gz file
