 Most node operations in Godot, such as drawing 2D, processing, or getting
-notifications are done in tree order, or top to bottom. For example, the
-top node in a scene has its ``_ready()`` function called first, then the
-node below it has its function called, then the node below that and so
-on. However, children of a node will get called before their parent, also
-in top to bottom order. So the top child node of the top node will get its
-``_ready()`` function called first.
+notifications are done in *tree order*, or top to bottom as seen in the 
+editor (also known as pre-order traversal):

-This can also be overridden using the ``process_priority`` node property.
-Nodes with a lower number are called first. For example, nodes with the
-priorities "0, 1, 2, 3" would be called in that order (from left to right).
+For example, the top node in a scene has its ``_process()`` function 
+called first, then the node below it has its ``_process()`` function called, 
+then the node below that and so on.
+
+An important exception is the ``_ready()`` function: each parent node has its
+``_ready()`` function called only after all its child nodes have their 
+``_ready()`` functions called, so that the parent knows its children are 
+completely ready to be accessed. This is also known as post-order traversal.
+In the above image, ``NameLabel`` would be notified first (but only after its
+children, if it had any!), followed by ``Name``, etc., and ``Panel`` would be
+notified last.

+The order of operations can also be overridden using the ``process_priority``
+node property. Nodes with a lower number are called first. For example, nodes
+with the priorities "0, 1, 2, 3" would be called in that order from left to right.
