Add minimum software requirements

 Running the GFS configurations (or almost any global workflow configuration except the coarsest) is a resource intensive exercise. This page discusses recommended HPC environmental settings and contact information in case you need assistance from a particular HPC helpdesk. While most of the documentation is based on supported NOAA platforms, the learnings here can hopefully apply to other platforms. 
 
+====================================
+Minimum system software requirements
+====================================
+
+The following system software requirements are the minimum for any new or existing system and reflect the development and testing environment on which the global workflow is maintained.  Any system that does not meet these requirements will not be supported.

 The S4 cluster is relatively small and so optimizations are recommended to improve cycled runtimes. Please contact Innocent Souopgui ([email protected]) if you are planning on running a cycled experiment on this system to obtain optimized configuration files.

-^^^^^^
-Merges
-^^^^^^
-
-Use the following command to have merge commits include the one-line description of all the commits being merged (up to 200). You only need to do this once on each machine; it will be saved to your git settings::
-
-   git config --global merge.log 200
-
-Use the ``--no-ff`` option to make sure there is always a merge commit when a fast-forward only is available. Exception: If the merge contains only a single commit, it can be applied as a fast-forward.
-
-For any merge with multiple commits, a short synopsis of the merge should appear between the title and the list of commit titles added by merge.log.

-Version

-It is advised to use Git v2+ when available. At the time of writing this documentation the default Git clients on the different machines were as noted in the table below. It is recommended that you check the default modules before loading recommended ones:
