 TODO: everything

-By default, LilyPond does a pretty jazz'n job of picking
-directions.  But in some cases, it may be desirable to force a
-direction.
-
+TODO: Maybe rename section to "directions".
+
+In typesetting music the direction and placement of many items is
+a matter of choice.  For example, the stems of notes can
+be directed up or down; lyrics, dynamics, and other expressive
+marks may be placed above or below the staff; text may be aligned
+left, right or center; etc.  Most of these choices may be left to
+be determined automatically by LilyPond, but in some cases it may
+be desirable to force a particular direction or placement.
+
+@unnumberedsubsubsection Default actions
+By default some directions are always up or always down (e.g.
+dynamics or fermata), while other things can alternate between
+up or down based on the stem direction (like slurs or accents).
+
+@unnumberedsubsubsection context layout
+Contexts are positioned in a system from top to bottom in the
+order in which they are encountered.  Note, however, that a
+context will be created implicitly if a command is encountered
+when there is no suitable context available to contain it.  For
+example,
+
+\contextAbove or whatever it is
