- * Helper class to access values on non-matching grids.
+ * @brief Communicate values between a mesh and arbitrary points
+ *
+ * This class enables evaluation of finite element functions defined
+ * on a Triangulation at arbitrary points inside the mesh. The underlying
+ * finite element mesh can be distributed among processes, which makes
+ * the operations more involved due to communication.
+ *
+ * The following helper functions for this class exist:
+ * VectorTools::point_values, VectorTools::point_gradients (the
+ * overloads taking an instance of RemotePointEvaluation). *
+ *
+ * @note Usage and implementation details of this class and the
+ * helper functions above are explained in detail in step-87.
*
* @note The name of the fields are chosen with the method
* evaluate_and_process() in mind. Here, quantities are
