+# Using the data
+
+All data is located in the `/data` folder as CSV files. There are two types:
+- Non-Enhanced: Raw data converted from MEPS into a plain CSV
+- Enhanced: Values for flags added to the dataset
+
+# Using the scripts
+
+To fetch more data from MEPS, you need R. The important functions are located in `/scripts/puf_download.R`. You can download data for any dataset if you have the PUF (ex: `HC-175E`). An example usage is as follows:
+
+```
+short_puf <- shorten_puf("HC-175E")
+download_puf(short_puf)
+# The file h175e.csv will be created in the current directory
+```
+
+All PUF files, regardless of what dataset they come from, can be downloaded through this command.
