+
+Installation, configuration and use of Mohawk tool is very
+straightforward. Mohawk has been primarily tested on Linux and Mac
+OS. Therefore, our installation instructions assume you are using
+Linux or Mac systems. We will test and release a windows version at a
+later time.
+
+Here are the steps to use Moahawk:
+
+1. Install NuSMV. You can obtain the NuSMV source code / binary from
+following site: http://nusmv.irst.itc.it/. 
+
+2. The Mohawk tool requires the latest version of JVM installed.
+
+3. Mohawk is a Java-based tool and is available as a jar file. You may
+either download the jar file from the website or build the jar file
+using the sources.
+
+Building jar file from sources:
+	 3.1 Compile the Java sources and create the jar file using
+	 the following ANT command : "ant dist". The build process
+	 creates the jar file in the directory work/dist. 
+
+The Mohawk tool can be run from commandline as follows (after
+completing step (1) and (2) ).
+
+    java -cp ./mohawk.jar mohawk.AbsRefine  <ARBAC SPECFile> 
+
+If Mohawk finds an error, Mohawk displays the counter example from
+NuSMV in the console. Mohawk writes the ARBAC spec used in each
+refinement step to a file with the following naming convention:
+rbacinstance<fileinstance>. Therefore, rbacinstance1 contains the
+abstract model verified in step 1.

data/casestudy/README

+This directory contains the ARBAC policies for a bank comprising 10,
+20, 30, and 40 branches. Please refer the actual casestudy for the
+detailed description, and the PDF file is available at:
+http://code.google.com/p/mohawk/downloads/detail?name=casestudy.pdf&can=2&q=.
+
+The policy files are available in the following two directories:
+
+1) Shallow - This directory contains the four policies with the "First
+Error".
+
+2) Deep - This directory contains the four policies with the "Second
+Error".
