 ## Learning more
 
-If you want to learn more about analysing dynamical systems, including chaotic behaviour, you can have a look at the textbook [Nonlinear Dynamics](https://link.springer.com/book/10.1007/978-3-030-91032-7). It utilizes DynamicalSystems.jl and provides a concise, hands-on approach to learning nonlinear dynamics and analysing dynamical systems [^3].
