Song Help Request transposing help

if the song on the guitar, for example, you are trying to transpose is using a capo on the second fret, do you take the picture of the guitar frets and make it two steps higher then transpose accordingly to the uke? or is there a different way

maybe its better to be straight up, i want to transpose john mayer's cover of free fallin, (guitar tabs)(the video), but there is a capo, can someone transpose this?
