How do I add measures to the beginning of a song

I have written a song I really love and I realize I need a few measures or bars of intro music before I start singing and I cannot figure out for the life of me how to add measures at the beginning of a song without messing everything up.

hi @Girlplusguitar, you can select a few measures at the beginning of your song by clicking the measure bar (numbered blocks above the melody staff), then clicking “add before” to add the same number of empty measures as you have selected
