 well:
 \begin{itemize}
-\item \verb|level distance|: vertical distance between the anchors of a parent and child
+\item \verb|level distance|: vertical distance between the anchors of a parent and its children
 \item \verb|sibling distance|: horizontal distance between the boundaries of sister subtrees (not the anchors of their roots, as in standard TikZ trees). Note that TikZ nodes already have some horizontal space around them (\verb|inner xsep|, by default \verb|0.3333em|), so even \verb|sibling distance=0pt| leaves some room.
-\item \verb|grow=up| or \verb|down|: trees grow up or down from their root. Other directions are not currently supported. The \verb|grow'| option is the same, but children appear clockwise with respect to their parent instead of counterclockwise.

+The \verb|grow=|\textit{direction}\/ and \verb|grow'=|\textit{direction}\/ options control the orientation of trees just as for standard TikZ trees. However, \textit{direction}\/ must be one of \verb|up|, \verb|down|, \verb|left|, or \verb|right|. The difference between \verb|grow| and \verb|grow'| is that \verb|grow| places children counterclockwise with respect to their parent and \verb|grow'| places them clockwise:

+Note that in sideways trees, \verb|level distance| is horizontal and \verb|sibling distance| is vertical. Sideways trees do take a little extra adjusting to look right, since the defaults are geared towards vertically growing trees. The meaning of the option \verb|execute at begin node=\strut| is, before typesetting the label of every node, insert the command \verb|\strut|, which is an invisible box that maximizes the height and depth of the node.

+For basic trees, \tikztree{} can be used as a drop-in replacement for Qtree, but most of Qtree's advanced features are either not accessed in the same way in \tikztree{} or not implemented at all. There is a package \verb|tikz-qtree-compat| which can be loaded to improve compatibility. Supported so far are:

+\item Superscripts and subscripts outside of math mode, and \verb|\automath|
+\item The \verb|\0|, \verb|\1|, and \verb|\2| commands, and \verb|\qtreeprimes|
+\item The \verb|\qroof| command
