+1 - It's a simple vhdl description of Patterson and Hennessy MIPS processor.
+
+2 - Arquitecture.pdf describe the processor like was done. To understand VHDL description it is highly recommend to follow the mentioned archive.
+
+3 - As you see it is not a complete FPGA project. It is just .vhd files. To run and simulate the processor we recommend the lecture of links above:
+
+	Download Xilinx ISE:
+		http://www.xilinx.com/products/design-tools/ise-design-suite.html
+	
+	Getting a license:
+		If you had problems during installation to generate your free license:
+		http://www.xilinx.com/support/licensing_solution_center.htm
+
+	Getting start with ISE:
+		www.xilinx.com/itp/xilinx10/books/docs/qst/qst.pdf
+
+4 - After install Xilinx ISE you will probably find it diffult to run it. 
+
+Concerning Ubuntu OS the following steps should be performed.
+
+		Open a terminal and enter:
+		
+		cd /opt/Xilinx/14.7/ISE_DS
+		sudo gedit run_ise.sh
+
+		Paste the following code in the end of file
+
+		#!/bin/bash
+		. /opt/Xilinx/14.7/ISE_DS/settingsXX.sh
+		ise
+
+		DON'T FORGET TO Replace settingsXX to your computer arquitecture.
+	
+		Save and close file.
+
+		Back in the command line, enter:
+
+		sudo chmod +x run_ise.sh   
+		As you now it makes the file executable
+
+		Enter:
+		ise 
+		We hope it is going to launch the Xilinx ISE software
