not starting to display data until next day will be considered later
in a follow-up issue.

+### Notes
+
+* To stop conky from inserting a blank line above the first line in **Usage** step 3, you can add `${lua load_fah_queue_info}` in step 2 on the first line in step 3 before any script function calls instead of adding it on its own line.
+* To set the frequency of updating the Folding@Home information, you can change the `throttle` value on line 68 of the script in file `fahqi.lua`. The default value is set to `5` so that the Folding@Home information will be updated once for every five conky updates, i.e. every 5th conky update.
