 # ReactionSystem
 
-A `ReactionSystem` represents a system of chemical reactions. Conversions are provided to generate corresponding chemical reaction ODE models, chemical Langevin equation SDE models, and stochastic chemical kinetics jump process models. As a simple example, the code below creates a SIR model, and solves the corresponding ODE, SDE, and jump process models.
