- * Use this class as follows:
+ * Usage of this class is explained in step-2 (without constraints) and step-6
+ * (with AffineConstraints) and typically looks as follows:
  * @code
  * DynamicSparsityPattern dynamic_pattern (dof_handler.n_dofs());
  * DoFTools::make_sparsity_pattern (dof_handler,
- *                                  dynamic_pattern);
- * constraints.condense (dynamic_pattern);
