The Gm7 is pretty easy, and the index plays both the first fret of the A and E strings. Make sure when pressing them down that both notes sound clear. After that the middle finger goes on the second fret of the C string. Use just the tip of the middle finger and make sure it is perpendicular to the fretboard. This will minimize any potential dead strings. And don’t forget to play the open G string as that is essential to the chord.
