+# The Mellanox MXM communication library
+
+## Overview 
+
+The Mellanox MXM communication library provides support for the Mellanox MXM interface for InfiniBand.
+
+## Installation
+
+For the module we use a RPM distributed by HP.
+
+1. Create new directory `/opt/psi/System/mxm/VERSION_merlin`
+1. Download RPM from https://downloads.linux.hpe.com/sdr/repo/mlnx_ofed/RedHatEnterpriseServer/
+1. Unpack RPM with `rpm2cpio RPM | cpio -i --make-dirs` somewhere
+1. copy all files from `opt/mellanox/mxm` to the module directory
+1. adapt directories in `lib/pkg-config/mxm.pc`
+1. add new variant to `files/variants`
+1. run the build-script to install the modulefile and to set the release
+ 
+
+> **Note:** The shared library `libmxm.so`provided by the RPMs for RHEL 6 cannot be used to compile other software.
+They requiry GLIBC >= 2.14, but on RHEL 6 only 2.12 is installed!
