+# DDNS Cloudflare - KeepUpIP
+#
+
+<#
+The script checks the current external IP based on defined websites. 
+In case of a change in the external IP, it updates the CloudFlare service using a dedicated API. 
+It requires providing 'api_key' and 'dns_zone' IDs. 
+Parameters, such as the number of logs set to 10k lines, can be customized.
+The frequency of execution should be defined in cron/schedule.
