+NARX Time Series Modelling
+--------------------------
+FastCan can be used for system identification.
+In particular, we provide a submodule `fastcan.narx` to build Nonlinear AutoRegressive eXogenous (NARX) models.
+For more information, check our `Home Page <https://fastcan.readthedocs.io/en/latest/?badge=latest>`_.
