The CTS description:

Experiencing the Extraordinary Form can raise a lot of questions. Why does the priest have his back to the congregation? Why is everything in Latin? How am I meant to take part? This booklet answers these questions so as to help Catholics get a better understanding of the Extraordinary Form and to engage with it in a fruitful way.
