+## Setting up
+
+If you want to try out the R code, you'll need to download the individual .CSV files of RePORTER data either at the link above or from the NIH website. Each .CSV file represents one year of data. I recommend making a folder structure like this:
+
+Top level folder: NIH_Data
+Folder within that top level folder: data 
+
+In that data folder, place your downloaded .CSV files. The code in the script will combine these into a single dataframe which you will work with by filtering the data and visualizing it by generating charts.
