 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
-    - `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.
-    - `03_make_figures.R` - This generates figures in a `figures/` directory in the repo.
+    - `01_set_extent.R` - This script sets the data directory and loads the extent from `extent.csv`.
+    - `02_download_data.R` - This will take the longest. It downloads the data to a `data/` directory in the repo. The whole of Wisconsin downloads ~12GB of data. This script can be skipped after you have already downloaded the data, and the extent is within what you downloaded.
+    - `03_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.
+    - `04_make_figures.R` - This generates figures in a `figures/` directory in the repo.
