 \section{\class{wxNode}}\label{wxnode}
 
-A node structure used in linked lists (see \helpref{wxList}{wxlist}).
+wxNodeBase is the node structure used in linked lists (see 
+\helpref{wxList}{wxlist}) and derived classes. You should never use wxNodeBase
+class directly, however, because it works with untyped ({\tt void *}) data and
+this is unsafe. Use wxNodeBase-derived classes which are automatically defined
+by WX\_DECLARE\_LIST and WX\_DEFINE\_LIST macros instead as described in
+\helpref{wxList}{wxlist} documentation (see example there). Also note that
+although there is a class called wxNode, it is defined for backwards
+compatibility only and usage of this class is strongly deprecated.
+
+In the documentation below, the type {\tt T} should be thought of as a
+``template'' parameter: this is the type of data stored in the linked list or,
+in other words, the first argument of WX\_DECLARE\_LIST macro. Also, wxNode is
+written as wxNode<T> even though it isn't really a template class -- but it
+helps to think of it as if it were.
