 1. Clone the repository
 2. Edit the extent of the map you want to produce in `extent.csv`. Include lat/long coordinates of two opposite corners (i.e. top-left and bottom-right).
 3. Run the scripts:
-- `01_download_data.R` - This will take the longest. The whole of Wisconsin downloads ~12GB of data. It downloads the data to a `data` directory in the repo
+- `01_download_data.R` - This will take the longest. The whole of Wisconsin downloads ~12GB of data
-- `02_process_data.R` - This loads and processes the data. After the initial run downloading the data for a given extent, you can start with this script.
