There are different approaches to modelling the divine, with each raising questions one needs to consider when employing them to produce a model. Outlining some of the most widely used methods is one of the goals of this Element, providing something of an introductory 'how-to' guide for theistic modelling. Through discussing what models are, the different sources of data acquisition, how to acquire data via reason, how to sort data, and what we might think a model provides us with, this Element aims to give readers the resources to take on the task of modelling informatively and effectively for themselves.
