-There are two different kinds of iterators for trees.
+There are two different kinds of iterators for trees: one for depth-first iteration and one for breadth-first iteration.
+
 The `CxTreeIterator` is performing a depth-first iteration with the capability of visiting a node twice:
 first when the iterator enters the node coming from its parent, and secondly when the iterator tracks back from its last child.
 This behavior is controlled via the `visit_on_exit` argument.

 On the other hand, the `CxTreeVisitor` performs a breadth-first iteration and visits every node only once.
 
+Both iterators do not support the removal of nodes.
+
 Since tree iteration needs to keep track of a stack (depth-first) or queue (breadth-first), internal memory is allocated.
 This memory is _automatically_ disposed of when the iteration _completes_.
 If you break from the iteration early, you must call `cxTreeIteratorDispose()` or `cxTreeVisitorDispose()`, respectively, to deallocate the memory.
