Just a comment that "quality manual" no longer exists in ISO 9001:2015. The intent of a "quality manual" is that you write something that describes about what your company does, how they do it, scope, context, interest parties, risk-based approach, metrics, measuring, PDCA, etc. etc. Don't regurgitate the standard.
With that said, ISO 13485:2016 read the first few sections 0 through 2 because a quality manual again takes on a more "what we do" approach. Take the core processes that your organisation and describe those. The describe the supporting processes, finally make sure you talk about all those things previously stated - what your company does, product they make, regulatory requirements, customer requirements, etc.
