Hi Aasif!
To get hold of a copy of the materials, you need to take the ICHD class. This is run fairly regularly online (in fact, I am teaching one this week in North America) and is sometimes also offered in a physical classroom (depending on demand).
I am not sure if we offer it in a Self-Study format, but I will ask a member of Genesys University's Sales team to reach out to you and advise you on options.
I look forward to (possibly) seeing you in class in the near future!
