In Chapter One on page 83 of Shantideva’s Bodhisattva-charyavatara below, you will find a 13-page introduction written by Tsoknyi Rinpoche entitled, The Bodhisattva-caryāvatāra: A Perfect Preparation for Vajrayāna Practice.  Here is the link: https://www.wisdomlib.org/buddhism/book/bodhisattvacharyavatara/d/doc4960.html

We are happy to be able to share this with you, through the generosity of Andreas Kretschmar:  Shantideva’s Bodhisattva-charyavatara, Entering the Conduct of the Bodhisattvas; accompanied by a translation of Drops of Nectar, an important Tibetan commentary on the Bodhisattva-charyavatara by Khenpo Kunpal (1862-1943) [Copyright ©Andreas Kretschmar 2003.  All Rights Reserved.]

Happy reading!
