+Pointer Operators (``&``, ``*``)
+================================
+
+The pointer operators ``&`` (reference) and ``*`` (dereference) are
+different from the bitwise math operator :ref:`&
+<lang-bitwisemath-and>` and the arithmetic operator :ref:`*
+<lang-arithmetic>`.
+
+Pointers are one of the more complicated subjects for beginners in
+learning C, and it is possible to write many useful Arduino sketches
+without ever encountering pointers. However, for manipulating certain
+data structures, the use of pointers can simplify the code, improve
+its efficiency, and generally provide many benefits that would be
+difficult to achieve without the use of pointers.
+
+Introducing pointers is somewhat outside the scope of this
+documentation.  However, a good `pointer tutorial
+<http://www.cplusplus.com/doc/tutorial/pointers/>`_ is available.
+Also see the `Wikipedia article on pointers
+<http://en.wikipedia.org/wiki/Pointer_%28computing%29>`_, especially
+the section on `pointers in C
+<http://en.wikipedia.org/wiki/Pointer_%28computing%29#C_pointers>`_.
