Any good resources for scripting custom functions with deluge

Hello,
are there any good resources for someone to start diving into scripting custom functions for automations with Deluge in Zoho Desk. I've read the articles in the KB, but when I want to write on my own I struggle.
Basically I'm looking to automate a reminder which automatically sends an email to the customer/contact of the ticket if the status is "Waiting on Customer" for more than 2days/48 hours.
Thanks for any tips or guidance.
