# Analysts Documentation This documentation is for people who just want to run the software on preconfigured machines. Spack-Manager deploys software through modules. The Spack-Manager infrastructure is designed to create time-stamped snapshots. Typically this will be done by system-administrators, but anyone building software can create snapshot modules or custom modules that can be shared. To use modules you need to add the location of the module files to your `MODULEPATH` environment variable. These are typically stored in the `$SPACK_MANAGER/modules` directory. You can execute the command ``` module use [path/to/modules] ``` to add the Spack generated modules to the list of available modules in your environment. The location of these module files on the major machines are: | Machine Name | Path | |--------------|------| | snl-hpc | `/projects/wind/spack-manager/modules` | | cee | `/projects/wind/spack-manager/modules` | | eagle | `/projects/exawind/exawind-snapshots/modules` |
