 and maximum memory allowed is ``Max.Mem/Node``.

+## Environment Modules
+
+On top of the operating system stack we provide different software using the PSI developed PModule system. 
+
+PModules is the official supported way and each package is deployed by a specific expert. Usually, in PModules
+software which is used by many people will be found.
+
+If you miss any package/versions or a software with a specific missing feature, contact us. We will study if is feasible or not to install it.
+
+### Basic commands:
+
+```bash
+module avail                                            # to see the list of available software packages provided via pmodules
+module load <package>/<version>                         # to load specific software package with a specific version
+module search <string>                                  # to search for a specific software package and its dependencies.
+module load <package>/<version> ... <package>/<version> # load the specific version of hdf5, compiled with specific version of gcc and openmpi
+module use unstable                                     # to get access to a set of packages not fully tested by the community
+module list                                             # to list which software is loaded in your environment
+```
+
+## When to request for new PModules packages
+
+#### Missing software
+
+If you don't find a specific software and you know from other people interesing on it, it can be installed in PModules. Please contact us
+and we will try to help with that. Deploying new software in PModules may take few days.
+
+Usually installation of new software are possible as long as few users will use it. If you are insterested in to maintain this software,
+please let us know.
+
+#### Missing version
+
+If the existing PModules versions for a specific package do not fit to your needs, is possible to ask for a new version.
+
+Usually installation of newer versions will be supported, as long as few users will use it. Installation of intermediate versions can
+be supported if this is strictly justified.
