-* LINUX INSTALLATION
+2- Downloading and Installing
+	
+	*** Note: If you have EXE or ZIP SansView installer, you don't need any of the following.
+	
+	2.1- System Requirements:
+		- Python version >= 2.5 and < 3.0 should be running on the system
+		- We uses Python2.5 - 2.7 for WIN, and Python2.6 - 2.7 for MAC
 
-	Create a directory where you want to install SansView. For example:
-		mkdir ~/my_username/sansview_dir
-		
-	Make sure that this directory is on the python path:
-		export PYTHONPATH=~/my_username/sansview_dir
-	
-	Download the .egg file and run the following:
-	
-	easy_install -d=~/my_username/sansview_dir sansview[...].egg
-	
-	SansView can then be started by calling:
-	
-	~/my_username/sansview_dir/sansview
+	2.2- Installing from source:
+		- Get the code from https://sansviewproject.svn.sourceforge.net/svnroot/sansviewproject/releases/sansview-x.x.x
+			- run 'python setup.py install' under the 'sansview-x.x.x' folder
+			- run 'python sansview.py' under the 'sansview' folder.
+		- The following modules are required:
+			* matplotlib >= 0.99.0(WIN), 0.99.1.1(MAC)
