**Updated README Documentation**
- Removed ANT build [description](url)
- Added Maven build description
- Add description howto trigger Maven build with Eclipse
- Add Maven build goals description
- Add description how to build and copy result to Protégé directory depending on Maven goals

**Changed Maven build**
- Removed Maven repository "prefuse" depency
- Restored previous used "prefuse.jar" and added as local Maven repository (like tablelayout)
- Add local Maven repository "prefuse" depency
- Added ANT task to copy the compiled jar to defined directory (if goal install is set)

Note: Both versions of prefuse available within the Maven repository seems to be not useable.

-ProtégéVOWL
-===========
-
-Source code of the VOWL plugin for Protégé. 
-
-Note that ProtégéVOWL has some known bugs and does not implement all visual elements defined in the VOWL specification. A more complete implementation of VOWL is provided by the web application [WebVOWL] (https://github.com/VisualDataWeb/WebVOWL).
-
-See http://vowl.visualdataweb.org for more information on ProtégéVOWL and WebVOWL.

-### Ant Usage
-
-To be able to run the ant build file properly you have to create a local file named 'local.properties' which will be ignored by the VCS. This file must contain at least the line 'protege.home=' followed by the path of Protege.

+
+## Developer Setup
+
+### Requirements
+Java JDK is required for the ProtégéVOWL build.
+
+### Eclipse Setup
+There are several options if you want to use Eclipse as IDE. You need to select the 
+``Import`` within Eclipse and select the ``Maven``, ``Existing Maven Projects`` option and select the ProtégéVOWL Git Repository. Eclipse will automatically suggest to import ``pom.xml``
+ 
+### Maven Build
+Some steps are required to build ProtégéVOWL with Maven. If you use Eclipse you need to run the ``pom.xml`` as Maven build and you may need to select JDK as Alternate JRE.
+In addition you need to add the goals ``clean compile package``. You will find the compiled packaged within the target folder.
+
+### Copy to Protege
+To copy the build result to your Protégé installation you need to add ``install`` to your maven goals.
+In addition you have to add the parameter ``protege.home`` which leads to your Protégé installation.
+If you remove the ``install`` goal the build result is not copied to Protégé.
