+To make the easiest possible transition from spreadsheet/dataset to REDCap, I have created a small app, which adds a graphical interface to the casting of a data dictionary and data upload. Install the package and launch the app as follows:
 
 ```{r eval=FALSE}
-require(REDCapCAST)
-shiny_cast()

+```
+
+The app primarily wraps one function: `ds2dd_detailed()`.

+```{r}

+    records = redcapcast_data,
+    metadata = redcapcast_meta,

-The app will launch in a new window and the interface should be fairly self-explanatory.
-The app only provides the most basic functionality, but might be extended in the future.
