Processing serial crystallography data with CrystFEL: a step-by-step guide

This article provides a step-by-step guide to the use of the CrystFEL software for processing serial crystallography data from an X-ray free-electron laser or a synchrotron light source. Whereas previous papers have described the theory and algorithms and their rationale, this paper describes the steps to be performed from a user perspective, including command-line examples.
