- * Rmd scripts for reporting the results of drake plans are in /Rmd
+ * drake::rmake(source = "_drake_XX.R") is run from inside a make_XX.R file
+ * the drake plan is kept inside _drake_XX.R along with the functions and package loading. This is not quite what the drake book recommends but it works for us
+ * Rmd scripts called by the drake plan in _drake_XX.R and used for reporting the results of drake plans are in /Rmd
  * outputs are kept in /docs (reports, plots etc)
