Are there any users of our R packages interested in working on cheatsheets like the ones RStudio has popularized? We would love to have these available for download on the websites for our R packages and this seems like a nice way for one or many users to contribute to the Stan project without needing to have a deep knowledge of the codebase (at least not the internals).

Here are some examples from RStudio:

and there’s even a template:

We would be interested in cheatsheets for any of the R packages we maintain, which at the moment include:

- rstan
- rstanarm
- brms
- bayesplot
- shinystan
- loo
- projpred
- rstantools

Another possible cheatsheet is one that focuses more broadly on the Stan ecosystem in R, showing how the various packages link up.
