 One of the main use cases of beastiary is accessing files on a remote server e.g. a high performance computer (HPC). Here we walk though the process of running beastiary on the University of Melbourne's HPC Spartan (although these steps apply to any remote server). This assumes beastiary is already installed on the remote server (e.g. `pip3 --user install beastiary`).
