     """
     An ExtensionArray for storing sparse data.
 
+    SparseArray efficiently stores data with a high frequency of a
+    specific fill value (e.g., zeros), saving memory by only retaining
+    non-fill elements and their indices. This class is particularly
+    useful for large datasets where most values are redundant.
+
     Parameters
     ----------
     data : array-like or scalar
         A dense array of values to store in the SparseArray. This may contain
         `fill_value`.
     sparse_index : SparseIndex, optional
+        Index indicating the locations of sparse elements.
     fill_value : scalar, optional
         Elements in data that are ``fill_value`` are not stored in the
         SparseArray. For memory savings, this should be the most common value
