+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>`_.
+
+
+Support Free-Threaded Wheels
+----------------------------
+FastCan has support for free-threaded (also known as nogil) CPython 3.13.
+For more information about free-threaded CPython, check `how to install a free-threaded CPython <https://py-free-threading.github.io/installing_cpython/>`_.
