Vocal Music Book

How do you play the guitar parts in books labelled with “piano/vocal/guitar”?
I just bought a music book for my girlfriend because I thought it would be fun for us to play music together (her on the piano, and me on the guitar).
However, I don’t understand how am I suppose to play the guitar part from the book…
I see the chords on top of the staves, but does that mean, for guitar, they only expect you to do strumming with chords?
So how do you play the guitar part in these kind of music books?
A perfect example is the song “Here come the sun” by the Beatles.
Like it has that little de-da-da-duh part..
like it doesn’t show how to play it in the book, as in there is no stave for guitar…
so I just play the chords?
Finger the chord shapes shown and arrpegiate them. That means to pick the notes separately. It makes it easier to play it this way. “Here Comes The Sun” is a very good song to play this way, because it’s the way it was written. 90 % of my music is, like your’s, “piano, vocal, guitar”. The music is just a publishing companies interpretation of the song, not a note-for-note transcription of what the artist wrote. They didn’t even play the songs the same way themselves two times in a row, it was all handled in the mixing room. George Harrison was a very accomplished musician and his passing was a sad day, indeed.
