# Basic Concepts

As already mentioned in [Introduction](/bare_metal_cpp/master.md), this book explains and shows examples of how to implement **soft** real time systems. This chapter will explain basic concepts of asynchronous event handling as well as how to implement required functionality without complex state machines, and/or task scheduing.
