 ## Reproducible Research
 When the Wats package is installed on your local machine, the [`Reproduce.R`](https://github.com/OuhscBbmc/Wats/blob/master/UtilityScripts/Reproduce.R) script starts with our initial datasets (ie, the vital statistics birth counts and the US Census population estimates) to create the derivative datasets and resulting graphs and analysis.
 
 ## Nonstandard Directories
 The following directories are not part of the standard R package:
+
  * `Datasets`: CSV versions of the *.rda data.frames officially included in the package.
  * `DocumentationForDevelopers`: Notes and links that should help package *developers* set up on their computer.  Typical package *users* won't have a need for this.
  * `PublicationGraphs`: A deprecated location that contains loose graphs of older versions of the manuscript.
