A good place for everyone starting with Microsoft Dynamics CRM or who wants to move into Dynamics 365 domain is the Dynamics 365 Customer Centre. This is aimed as Dynamics 365 Customers including users and advanced users. This is not a Technical or IT professionals focused site as there are other sites dedicated to these subjects.
You can find Dynamics 365 Customer Centre here: https://www.microsoft.com/en-US/Dynamics/crm-customer-center/default.aspx
The Customer Centre is literally filled with Dynamics 365 user guides, Dynamics 365 ebooks, Dynamics 365 videos and more.
I strongly encourage individuals at an early stage of learning Dynamics 365 to have a look and review the customer centre.
Hope this helps!
