 ## **Linux Build Instructions**
 
+### Pre-requisites
+
+* GIT client: Available from https://git-scm.com/downloads
+* GCC 4.9 compiler or XCODE compiler
+
+Create a new directory for an EDK II WORKSPACE.
+
+The code block below shows the GIT clone operations required to pull the edk2
+repository, and the edk2-test branch from the edk2-staging repository.
+
+Next it sets environment variables that must be set before running
+```edksetup.bat```. Since content is being pulled from multiple repositories,
+the EDK II [Multiple Workspace](
+https://github.com/tianocore/tianocore.github.io/wiki/Multiple_Workspace)
+feature is used.
+
+Next, the ```edksetup.bat``` file is run to complete the initialization of an
+EDK II build environment.  Two example build commands are shown.  The first one
+in ```TestFrameworkPkg/TestFrameworkPkg.dsc``` builds a test harness and creates
+an installer in the build output directory.  The second one in
+```TestCasePkg/TestCasePkg.dsc``` builds a sample test case using a test library
+from the ```TestFrameworkPkg``` and adds the test case to the installer in the
+build output directory.
