An adjustable golf club incorporates instructions into the golf club, and more particularly, in connection with the club head. More specifically, encoded information is visibly provided on the club head, the encoded information relating to the performance of the club head. In addition to the encoded information, a decoder or device for interpreting the encoded performance information is also provided on the club head. The encoded information, in conjunction with the decoder, allows the golfer to easily adjust his or her club head based on playing conditions or his or her swing. Typically, the encoded information relates to a weight of the club head, and may be used to vary the weight of the club head. A method of configuring a putter-type golf club head adaptable to a plurality of configurations is described, as well as a kit for selectively configuring components of a golf club head.
