are to be ignored.
+@subsubheading Adding syllables to grace notes
+
+By default, grace notes (e.g. via @code{\grace}) do not get assigned
+syllables when using @code{\lyricsto}, but this behavior can be
+changed:
+
+@lilypond[verbatim,ragged-right,quote]
+\relative c' {
+ f4 \appoggiatura a32 b4
+ \grace { f16[ a16] } b2
+ \afterGrace b2 { f16[ a16] }
+ \appoggiatura a32 b4
+ \acciaccatura a8 b4
+}
+\addlyrics {
+ normal
+ \set includeGraceNotes = ##t
+ case,
+ gra -- ce case,
+ after -- grace case,
+ \set ignoreMelismata = ##t
+ app. case,
+ acc. case.
+}
+@end lilypond
+
+@knownissues
+Like for @code{associatedVoice}, @code{includeGraceNotes} needs to be
+set at latest one syllable before the one which is to be put under a
+grace note. For the case of a grace note at the very beginning of a
+piece of music, consider using a @code{\with} or @code{\context}
+block:
+
+@lilypond[verbatim,ragged-right,quote]
+<<
+ \new Voice = melody \relative c' {
+ \grace { c16[( d e f] }
+ g1) f
+ }
+ \new Lyrics \with { includeGraceNotes = ##t }
+ \lyricsto melody {
+ Ah __ fa
+ }
