How Do You Pray a Decade of the Catholic Rosary?

To pray one decade of the rosary, first make the sign of the cross and say one "Our Father" and 10 "Hail Mary"s, then say one "Glory be to the Father" and meditate on one of the 20 Mysteries. The mysteries to meditate about include the Joyful, Sorrowful, Glorious and Luminous Mysteries.
