+Note: PART I and PART II can be skipped if you have already done that.
+
+Part I: Base environment setup
+I-1. install JDK
+  sudo zypper install java-1_6_0-openjdk
+
+I-2. install X11 related packages for eclipse running
+  sudo zypper install xorg-x11-xauth
+
+I-3. using git through a SOCKS proxy(If you're behind some firewall)
+I-3.1 Create a wrapper script for netcat
+  cat > ~/bin/proxy-wrapper
+
+  #!/bin/sh
+  PROXY=proxy-jf.intel.com
+  PORT=1080
+  METHOD="-X 5 -x ${PROXY}:${PORT}"
+
+  nc $METHOD $*
+
+  Then Ctlr+D to save the file and "chmod +x ~/bin/proxy-wrapper"
+
+  Note: if netcat is not installed, please "sudo zypper install netcat-openbsd".
+
+I-3.2 set git proxy environment
+  add the following line to your ~/.bashrc and "source ~/.bashrc"
+
+  export GIT_PROXY_COMMAND="/somepath/bin/proxy-wrapper"
+
+  Please be noted that it should be absolute path, since "~" is not supported.
+
+I-4. using svn through a http_proxy(If you're behind some firewall)
+  Modify the ~/.subversion/servers
+
+  http-proxy-host = proxy.jf.intel.com
+  http-proxy-port = 911
+
+I-5. Get the scripts from eclipse-poky git
+  git clone git://git.pokylinux.org/eclipse-poky.git
+
+  The scripts used for auto builder is under the directory of "scripts".
+
+
+Part II: Setup the build environment
+II-1. Modify the scripts/setup.sh to set appropriate proxy settings.
+  Set PROXY to a http proxy URL and PORT to the port number. Comment out 
+  these 2 variables if proxy is not required.
+
+II-2. Run scripts/setup.sh to set up the build environment. 
+  This will install the eclipse and relevant plugins required to build 
+  Yocto eclipse plug-in.
+
+Part III: Build & Install Yocto Eclipse plug-in
+
+To build the Yocto Eclipse plug-in, simply run 
+"ECLIPSE_HOME=<eclipse path> scripts/build.sh <branch name> <release name>".
+
+The <eclipse install path> is the absolute path where you installed the 
+eclipse in step II-2.
+
+The <branch name> is the git branch name you build based on.
+
+If successful, 2 files org.yocto.sdk-<release name>-<date>.zip and 
+org.yocto.sdk.-<release name>-<date>-archive.zip will be genereated under the
+directory where you invoked the "build.sh" script.
+
+The file with the "-archive" in its name is the archive zip used for eclipse
+update manager. User should use eclipse update manager to install it.
+
+The file without the "-archive" in its name is the zip containing only the 
+plugins/features. User should unzip it to the their target eclipse to install it.
