+Build Instructions
+==================
+
+The build of the workbench is maven-based, with a set of special build plugins called [Tycho](http://tycho.sonatype.org/).
+
+The snapshot repository for Tycho and all it's particulars are configured in the parent pom.xml file in this directory. Maven 3 and Java are required.
+
+Install the Eclipse Publisher Patch for the Mac OS
+--------------------------------------------------
+
+There is a specially patched Eclipse plugin file that is needed for any Mac OS build at the moment. You will have to
+deploy this file into your local maven repository manually. Take the following step:
+
+Copy /etc/org.eclipse.equinox.p2.publisher_1.1.2.v201012021428.jar to the following location:
+.m2/repository/org/sonatype/tycho/tycho-p2-runtime/0.11.0-SNAPSHOT/eclipse/plugins
+
+.m2 above is the location of your own local Maven repository. The patched file will be used instead of the existing plugin.
+
+Build the Product and Repository
+--------------------------------
+
+The distributable ZIP files and update site are all created in one maven command:
+
+mvn install
+
+or
+
+mvn clean install
