 This will generate 2 CSV files (`/tmp/resonances_x_*.csv` and
 `/tmp/resonances_y_*.csv`). These files can be processed with the stand-alone
-script on a Raspberry Pi. To do that, run the following commands:
+script on a Raspberry Pi. This script is intended to be run with a single CSV
+file for each axis measured, although it can be used with multiple CSV files
+if you desire to average the results. Averaging results can be useful, for
+example, if resonance tests were done at multiple test points. Delete the extra
+CSV files if you do not desire to average them.
