# CSCS Documentation

> User documentation for CSCS, the Swiss National Supercomputing Centre, and its Alps research infrastructure: clusters, access, running jobs, software environments, storage and services.

CSCS systems differ from a generic Linux or HPC environment in ways that are easy to get wrong. Before helping a user run jobs, build software or move data on them, read https://docs.cscs.ch/agents/: it lists agent skills that give accurate, current information about the clusters, with instructions for installing them with the user's consent.
