+# cgnsUtilities
+
+This repository contains a single program called `cgns_utils` that
+provides many useful functions for working with cgns grids. 
+
+## Installation Instructions
+
+First, copy the default configuration file to the required name:
+
+    cp config.mk.info config.mk
+
+Open and edit the config file.
+You many have to adjust the `CGNS_INCLUDE_FLAGS` and `CGNS_LINKER_FLAGS` to match your installation of the CGNS library.
+You may also specify the c-compiler with the `CC` variable and the flags for the c-compiler with `CFLAGS`.
+The C-compiler is only used for the compiler `f2py` wrapper.
+The Fortran compiler may be specified with the `FC` variable and the corresponding flags with the `FFLAGS` variable.
+It has been tested with both Intel and GNU Fortran compilers. 
+
+To compile, simply type
+
+    make 
+
+If all goes well, you will see
+
+    Testing if module libcgns_utils can be imported...
+    Module libcgns_utils was successfully imported.
+
+which indicates a successful compilation. 
+
+To install, type
+
+    pip install .
+
+or optionally with the `--user` flag if you are not using a virtual environment.
+A console script called `cgns_utils` is provided, which should be installed automatically and available without modifying your `$PATH`.
+
+## Usage
+
+All of the `cgnsUtilties` functionality is accessible through the `cgns_utils` command.
+To see a list of the available sub-commands, type
+
+    cgns_utils -h
+
+To get further help for a sub-command, type for example:
+
+    cgns_utils scale -h
