 Compiler: 
 
-you will need the Windows SDK 7.1 compiler, which you can find at the following link
+You need Visual Studio Express 2010 for C++, which you can find here: 
+http://www.microsoft.com/visualstudio/en-us/products/2010-editions/visual-cpp-express
+
+you will also need the Windows SDK 7.1 compiler, which you can find at the following link
 http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=8279
 This compiler is compatible with Matlab, as detailed in the following webpage: 
 http://www.mathworks.com/support/compilers/R2011b/win64.html#n2
+
+Be careful not to download the sdk before Visual Studio Express, as this could lead to 
+environment setup issues. 
+
+
+Before you do anything related to ISSM! You have to capture the settings of your compiler.
+This is by far the most tricky part. 
+
+Follow Figure 2 for more details. You have to launch sdk 7.1 command prompt, go to the 
+cygwin directory and fire up Cygwin by executing Cygwin.bat. Once this is done,dump the 
+results of the export command onto a file, called  sdk7.1.win7.64.sh 
+you will need this file later in the ISSM install.

+Getting the cl.exe compiler to work: 
+before trying to compile the externalpackages, you need to be sure that your compiler cl.exe 
+(the sdk compiler)works. To make sure, create a simple hello world file: 
+
+hello.cpp
+
+#include <stdio.h>
+int main(){
+printf("%s\n","hello");
+return 1;
+}
+
+and try to compile it by doing: 
+cl hello.cpp
+
+If this does not work, do not go any further! The settings of your cl compiler are found 
+in externalpackages/windows/configs/ 
+if there is a significant different between you sdk7.1.win7.64.sh file (see above section Compiler) 
+and the file that is being sourced in the windows/configs directory, place your new file in 
+the configs directory. Relaunch bash, and try to run cl hello.cpp again. Beware, you might 
+have to erase some lines in your file, as cygwin might not like some of the stuff that your 
+Windows platform is trying to define. 
+
+
+
+
+Once the cl.exe compiler works, you can start installing the following packages: 
+petsc   metis triangle and cccl
+
+For petsc, use install-3.1-win7.sh 
+For metis, use install-4.0-win7.sh
+For cccl, use install-win7.sh
+For triangle, use install-win7.sh
+
+Once these externlapackages have been compiled, you can compile issm: 
+
+./scripts/autoremakererun.sh
+./configs/config-win7-64.sh
+make install
+
+This should compile both parallel and serial versions of ISSM. Beware though, the parallel
+version cannot be run on multi-core platforms yet! We are actively working on it. 
+
+
+
+
+
+One note about 32 vs 64 bit compile: 
+depending on your Matlab version, you will need to do a 32 or 64 bit compile. The only 
+difference between both compiles is the setup of the cl.exe compiler. For ease of use, 
+you will find in externalpackages/windows/windows_environment.sh a switch to go from 32 
+to 64 bit compile. When you type cl.exe \help at the command prompt, cl.exe should report 
+what system it is compiling for. 
+Beware, switching 32 to 64 or vice-versa implies recompiling everything from scratch.
