+CustomAlertScript.py
+
+This is an example script that can be ran by cron at custom intervals.
+This script is a simplifies version of the AlertScript function included in SkywarnPlus.
+It will check the last alerts from SkywarnPlus and execute commands associated with them.
+
+The purpose of this is to allow you to run AlertScript commands at custom intervals,
+rather than only running commands when alerts are first detected.
+
+Example:
+Trigger SkyDescribe.py for all alerts that contain the word "Warning" in the title, once per hour.
+Crontab entry: 0 * * * * /usr/local/bin/SkywarnPlus/CustomAlertScript.py
+
+You can create as many copies of this script as you want to execute different commands at different intervals.
