     ----------
     optimizer : optimizer object, optional
         Optimization method used to fit the SINDy model. This must be an object

+        extending the ``sindy.optimizers.BaseOptimizer`` class. Default is
         sequentially thresholded least squares with a threshold of 0.1.
 
     feature_library : feature library object, optional
+        Feature library object used to specify candidate right-hand side features.
+        This must be an object extending the

         Default is polynomial features of degree 2.

     feature_names : list of string, length n_input_features, optional
-        Names for the input features. If None, will use ['x0','x1',...].

     discrete_time : boolean, optional (default False)
         If True, dynamical system is treated as a map. Rather than predicting
         derivatives, the right hand side functions step the system forward by
         one time step. If False, dynamical system is assumed to be a flow

     n_jobs : int, optional (default 1)
         The number of parallel jobs to use when fitting, predicting with, and
