+REDCapRITS also works with the data export script (a.k.a., *syntax file*) supplied by REDCap. Here is an example of its usage:
+
+```r
+# You must set the working directory first since the REDCap data export script
+# contains relative file references.
+setwd("/path/to/data/")
+
+# Run the data export script supplied by REDCap.

 1. Run the macro call `%REDCAP_SPLIT()`. You will have an output dataset for
 your main table as well as for each repeating instrument.
 
+#### Examples
+
+Please follow the instructions from REDCap on importing the data into SAS. REDCap provides the data in a *csv* format as well as *bat* and *sas* files. The instructions are available when exporting the data from the REDCap web interface. If you do not use the pathway mapper (*bat* file) provided, you will need to go into the *sas* file provided by REDCap and alter the file path in the `infile` statment (Line 2).

+```sas
+* Run the program to import the data file into a SAS dataset;
