+========================================
+
+The README is used to introduce the module and provide instructions on
+how to install the module, any machine dependencies it may have (for
+example C compilers and installed libraries) and any other information
+that should be provided before the module is installed.
+
+A README file is required for CPAN modules since CPAN extracts the
+README file from a module distribution so that people browsing the
+archive can use it get an idea of the modules uses. It is usually a
+good idea to provide version information here so that people can
+decide whether fixes for the module are worth downloading.
+
+INSTALLATION
+
+To install this module type the following:
+
+   perl Makefile.PL
+   make
+   make test
+   make install
