I'm looking at this page:
https://docs.microsoft.com/en-us/dynamics365/customerengagement/on-premises/customize/overview
it seems to be the main entry point for the documentation on how to customize Dynamics CRM, but it refers to the product as "Dynamics 365 Customer Engagement (on-premises)". There doesn't seem to be any note explaining why this only applies to on-premise versions, and I can't find any equivalent documentation discussing customization of the cloud version.
Can anyone throw any light on this please?
