 ## Proposed interface
 
-We are an proposing an dinterface similar to what is used in `{rstanarm}` and `{distributions3}`, where probability distributions are called according to their capitalised names. This avoids masking `base::gamma()` (although we still mask `stats::Gamma`). There is potential for integration especially with `{distributionS3}`. Parameters are nested according to the same syntax.
