+MPAS
+====
+
+MPAS is a collaborative project for the rapid development and prototyping of
+dynamical cores. A shared framework provides infrastructure typically required
+by model developers, including communication routines, and I/O routines. By
+using MPAS, developers can leverage pre-existing code and focus more on
+development of their model.
+
+
+Code Layout
+----------
+
+Within the MPAS repository code is laid out as follows. Sub-directories are only described below the src directory.
+
+	MPAS
+	├── graphics
+	│   ├── dx -- Graphics for OpenDX
+	│   ├── matlab -- Graphicx for MATLAB
+	│   └── ncl -- Graphics for NCAR Command Language
+	└── src
+	    ├── registry -- Code for building Registry.xml parser (Shared)
+	    ├── driver -- Main driver for MPAS in stand-alone mode (Shared)
+	    ├── external -- External software for MPAS (Shared)
+	    ├── framework -- MPAS Framework (Includes DDT Descriptions, and shared routines. Shared)
+	    ├── operators -- MPAS Opeartors (Includes Operators for MPAS meshes. Shared)
+	    ├── inc -- Empty directory for include files that Registry generates (Shared)
+	    └── core_* -- Individual dynamical cores. (Private)
+
+
+Dynamical cores are private and typically developed independently. Each core is stored in a separate directory under src, with an abbreviated name. For example:
+
+src/core_sw houses the shallow water core.
+
+For information about building and running each core, please refer to the specific users guide for each cores.
