+Step 0: Getting GPGPU-Sim
+=========================
+To get GPGPU-Sim, you need git (a widely used source code management system)
+to be installed on your system.
+Run the following command to get the source code of GPGPU-Sim for the first
+time:
+
+git clone git://dev.ece.ubc.ca/gpgpu-sim
+
+If you have already obtained GPGPU-Sim and would like to get the latest updates
+and bug fixes, run the following command in the root directory of GPGPU-Sim:
+
+git pull
+
+While pulling the latest changes, conflicts might arise due to changes that you
+made to your codebase that conflict with the latest updates. In this case, you
+need to resolved those conflicts manually. You can either edit the conflicting
+files directly using your favorite text editor, or you can use the following
+command to open a graphical merge tool to do the merge:
+
+git mergetool
