Is there any "Getting started" or HOWTO for EPICS 7?

Hi!

    Is there any "Getting started with EPICS7" or "EPICS7 for dummies" 
or such, to get acquainted with version 7 new features?

        For example, for EPICS3 there are two essential presentations:
1. "Introduction to Channel Access Clients"
https://epics.anl.gov/docs/GSWE/developtools/EPICSTraining.IntroductionToChannelAccessClients.pdf 

2. "Writing EPICS Drivers (and Device Support)"
https://epics.anl.gov/meetings/2009-07/talks/em_WritingEPICSDrivers.ppt

    We, the BINP SKIF control system team, plan to use EPICS7 because 
of its richer type system, namely the following features:
1. 64-bit integer and unsigned 32-bit integer types.
2. Variable-length arrays.
3. Structured types.
But we are completely lost on how to deal with these novelties at C level.

    Are there any documents how to get started with C/C++ client API 
and Driver/Device support API?

With best regards,
