You should xref to "SMIE Tricks", if that is what you are referring to.
In general, it is good to add xrefs to the introduction, even if there
are links to the same nodes in the menu below that introduction, because
that makes it clearer to the reader exactly where to find the more
detailed treatment of each statement in the introduction.

Also, it would be nice to have a better description of what kinds of
languages it's practical to use SMIE for.
