The C4 model is an "abstraction-first" approach to diagramming software architecture, based upon abstractions that reflect how software architects and developers think about and build software. The small set of abstractions and diagram types makes the C4 model easy to learn and use. Please note that you don't need to use all four levels of diagram; only those that add value - the System Context and Container diagrams are sufficient for many software development teams.
