         Trim values at input threshold(s).
 
+        Assigns values outside boundary to boundary values. Thresholds
+        can be singular values or array like, and in the latter case
+        the clipping is performed element-wise in the specified axis.
+
         Parameters
         ----------
         lower : float or array_like, default None
+            Minimum threshold value. All values below this
+            threshold will be set to it.
         upper : float or array_like, default None
+            Maximum threshold value. All values above this
+            threshold will be set to it.
         axis : int or string axis name, optional
             Align object with lower and upper along the given axis.
         inplace : boolean, default False
