There are two examples in the projpred source code, that use `init_refmodel()` to define reference models for `rstanarm` and `brms` models (see for example [https://github.com/stan-dev/projpred/blob/181606a416471f8145976e8b048d5213b9fb6ab3/R/refmodel.R#L116](https://github.com/stan-dev/projpred/blob/181606a416471f8145976e8b048d5213b9fb6ab3/R/refmodel.R#L116)). By following those functions, you’ll see how to set up the various parameters expected by `init_refmodel()`.

Having said that, I agree that documentation could be improved on that front! :)
