We recommend that you start with the introductory tutorials on the PyLith wiki page found here:

Navigate to the Tutorial section to see recordings of prior tutorials. A good starting point is to follow the Pre-Workshop instructions for the 2017 Crustal Deformation Workshop here:

We will be offering this workshop again 10-14 June 2019. Please continue to watch this category for the announcement when registration is open.
