This document provides a guide for those associated with the MoEDAL Collaboration who wish to use the Worldwide LHC Computing Grid (WLCG) resources for collaboration activities, including (but not limited to) running simulations, storing experimental and simulated data, and analsying the results for publication. The guide is largely based on a similar guide written for the UK's GridPP Collaboration that covers a suite of software tools and infrastructure developed or adopted for the benefit of user communities new to the Grid, namely GridPP DIRAC, Ganga, and CernVM. It focusses largely on running GEANT4 simulations of the MoEDAL experiment, with the MoEDAL software deployed with the CernVM File System (CernVM-FS or CVMFS), job and data management with the GridPP DIRAC instance, and Ganga (running on a CernVM) as the Grid User interface.

This work was supported by the UK Science and Technology Facilities Council (STFC) via grant numbers ST/J000256/1 and ST/N00101X/1, as well as a Special Award from the Royal Commission for the Exhibition of 1851. The CERN@school Collaboration would also like to acknowledge the support provided by the GridPP Collaboration in terms of both computing resources and technical guidance from collaboration members.
