-====== Environment Modules ======

-[[http://modules.sourceforge.net|Environment Modules]] are designed to manage custom package installations.  Software in our department is all installed to a network filesystem mounted over NFS where each package available is installed to it's own directory.  This allows us to manage a wide range of software across different Linux distributions without users having to deal with any configuration.  We can include different versions of software, letting users choose which they want to use.
+[[http://modules.sourceforge.net|Software Modules]] make it easy for you to use software installed on our Linux systems. We provide a wide range of software across all our servers so that you don't have to install software on your own.  We also offer different versions of software, letting users choose which they want to use.

-===== Things to keep in mind =====
+=== Shell Scripting/Slurm Batch ===
-==== Shell Scripting/Slurm Batch ====
 If you write shell scripts or slurm batch files that make use of these software packages, remember that you must still load modules from inside of your script.  For example, your script must contain the line ''%%module load python3%%'' before you can use python from inside of your script.
