+To reproduce Figures 3, 4, and 5 of that paper:
+1) Install [Python 3.9](https://www.python.org/downloads/release/python-390/).
+2) Run `pip install -r requirements.txt`. You may want to do this within a [virtual environment](https://docs.python.org/3/tutorial/venv.html).
+3) To reproduce Figure 3, run:
 
     python figure_3.py
 
-This may take a few hours to run.
+This took us ~30 minutes to run.
 
 To reproduce Figure 4, run:
 
     python figure_4.py
 
-This may take a few hours to run.
+This took us ~4 hours to run.
 
 To reproduce Figure 5, run:
 
     python figure_5.py
 
-This should run nearly instantaneously.
+This took us ~1 second to run.
+
+We ran these scripts on an Ubuntu laptop with Intel Core i7-10750H CPU.
