There are many resources out on the Web.

I hope that helps.

Do you want the traditional Franciscan Crown dictated by Our Lady or one of the modern versions?

The original from Our Lady, was a circle (the shape of a crown)of seven decades of Hail Marys separated by seven Our Father beads.  NO Creed, nor Glory Be and not the Fatima Prayer.

Shortly after the Franciscans added a pendant to the circle containing  two Hail Mary beads, a space, an Our Father bead, a space, and a final Hail Mary bead ending with the Crucifix. (the first Our Father before the first decade was then moved to the pendant also)

The two additional Hail Marys were to bring the total Hail Marys prayed to seventy-two, the number of years they thought Our Lady lived. (St. Brigitte thought sixty-three with her rosary) and the last Our Father and Hail Mary were for the Pope to gain the indulgences that had now been attached to the Crown.  
This all happened about the same time the Franciscans added the second half to the Hail Mary itself. (that is why when the Anglicans pray the rosary their Hail Mary is still just the first half).

To gain the indulgences you only have to announce each Joy, no meditation is required.
Sadly the modern versions have adapted the pendant and prayers from the St. Bridgette and Dominican rosaries
