This document covers the complete AccelStepper library ecosystem, including the core AccelStepper class for single motor control and the MultiStepper class for coordinated multi-motor operations. An instance is really nothing more than a pointer to an object. The stepper object should be created in the global scope (that is, outside of setup() or loop()). Continuous rotation mode is kind of a bonus mode, if you just want to run the stepper continuously (although the code for that is somewhat trivial and doesn't need a library). To use it, you construct (or "instantiate" in C++ speak) named objects of AccelStepper type.
