 [![Build Status](https://openpower.xyz/buildStatus/icon?job=openbmc-build)](https://openpower.xyz/job/openbmc-build/)
 
-## Building ##
+The OpenBMC project can be described as a Linux distribution for embedded
+devices that have a BMC; typically, but not limited to, things like servers,
+top of rack switches or RAID appliances. The OpenBMC stack uses technologies
+such as Yocto, Open-Embedded, Systemd and DBus to allow easy customization
+for your server platform.
 
-OpenBMC uses Yocto/Open-Embedded for a build system, which supports an
-out-of-tree build.  It is recommended that you create an empty directory
-somewhere to hold the build.  This directory will get big.
 
-On Ubuntu 14.04 the following packages are required to build the default target
+## Setting up your OpenBMC project ##
 
-    sudo apt-get install -y git build-essential libsdl1.2-dev texinfo gawk chrpath diffstat
+### 1) Prerequisite ###
+- Ubuntu 14.04
 
-On Fedora 23 the following packages are required to build the default target:
+```
+sudo apt-get install -y git build-essential libsdl1.2-dev texinfo gawk chrpath diffstat
+```
 
-    sudo dnf install -y git patch diffstat texinfo chrpath SDL-devel bitbake
-    sudo dnf groupinstall "C Development Tools and Libraries"
+- Fedora 23
 
-To start a build:
+```
+sudo dnf install -y git patch diffstat texinfo chrpath SDL-devel bitbake
+sudo dnf groupinstall "C Development Tools and Libraries"
+```
+### 2) Download the source ###
+```
+git clone git@github.com:openbmc/openbmc.git
+cd openbmc
+```
 
-    cd <builddir>
-    . <repodir>/openbmc-env
-    bitbake obmc-phosphor-image
+### 3) Target your hardware ###
+Any build requires an environment variable known as `TEMPLATECONF` to be set
+to a hardware target.  OpenBMC has placed all known hardware targets in a
+standard directory structure `meta-openbmc-machines/meta-openpower/[company]/[target]`.
+You can see all of the known targets with `find meta-openbmc-machines -type d -name conf`.
+Choose the hardware target and then move to the next step. Additional examples
+can be found in the [OpenBMC Cheatsheet] (https://github.com/openbmc/docs/blob/master/cheatsheet.md)
+
+Machine | TEMPLATECONF
+--------|---------
+Palmetto | ```meta-openbmc-machines/meta-openpower/meta-ibm/meta-palmetto/conf```
+Barreleye | ```meta-openbmc-machines/meta-openpower/meta-rackspace/meta-barreleye/conf```
+Zaius| ```meta-openbmc-machines/meta-openpower/meta-ingrasys/meta-zaius/conf```
+Witherspoon| ```meta-openbmc-machines/meta-openpower/meta-ibm/meta-witherspoon/conf```
+
+
+As an example target Palmetto
+```
+export TEMPLATECONF=meta-openbmc-machines/meta-openpower/meta-ibm/meta-palmetto/conf
+```
+
+### 3) Build ###
+
+```
+. openbmc-env
+bitbake obmc-phosphor-image
+```
+
+Additional details can be found in the [docs](https://github.com/openbmc/docs)
+repository.
+
+## Build Validation and Testing ##
+Commits submitted by members of the OpenBMC Github community are compiled and
+tested via our [Jenkins](https://openpower.xyz/) server.  Commits are run
+through two levels of testing.  At the repository level the makefile `make
+check` directive is run.  At the system level, the commit is built into a
+firmware image and run with a arm-softmmu QEMU model against a barrage of
+[CI tests](https://openpower.xyz/job/openbmc-test-qemu-ci/).
+
+Commits submitted by non-members do not automatically proceed through CI
+testing. After visual inspection of the commit, a CI run can be manually
+performed by the reviewer.
+
+Automated testing against the QEMU model along with supported systems are
+performed.  The OpenBMC project uses the [Robot Framework]
+(http://robotframework.org/) for all automation.  Our complete test
+repository can be found [here](https://github.com/openbmc/openbmc-test-automation).
+
+## Submitting Patches ##
+Support of additional hardware and software packages is always welcome.
+Please follow the [contributing guidelines](https://github.com/openbmc/docs/blob/master/contributing.md)
+when making a submission.  It is expected that contributions contain test
+cases.
+
+## Bug Reporting ##
+[Issues](https://github.com/openbmc/openbmc/issues) are managed on
+Github.  It is recommended you search through the issues before opening
+a new one.
