From Ancient Civilizations: The Popol Vuh Legacy

Many versions of the creation must have circulated among the Mayas, but the only one that survives in a written form is the Classical K'iche' version in the Popol Vuh, title that literally means "book of the mat." Throughout Mesoamerica mats, or petates, were symbols of the kings' authority and power and were used to sit on by governors, high-ranking courtiers and heads of lineages. For this reason, the title of the book has been interpreted  as the Council Book.

The names of its authors are unknown, but evidence indicates it was written by prominent members of the K'iche' nobility from Q'umarkaaj, which ruled a vast region of the Guatemalan highlands during the time of the Spanish conquest. Written in a brilliant poetic style, it is also a masterpiece in literary terms.

The Popol Vuh presents a mythological version of the creation of the world, followed by the adventures of the twin gods, Hunahpu and Xbalanque, that take place in a primordial age before the creation of the first human beings. The triumphs of the heroes over primeval forces and the gods of death give way to the creation of man from maize. The second part of the text concentrates on the origins of the governing lineages of the K'iche' kingdom, their migration to Guatemala's highlands, their territorial conquests, the founding of their principal city, and the history of their kings up until the time of the Spanish conquest.

The Popol Vuh is a corpus of myth-historical narratives and encompasses a range of subjects that includes creation, ancestry, history, and cosmology. In Spanish, the major reference continues to be the translation made by Adrian Recinos. 
Despite the technological advancements and foreign culture influences, the Maya descendants are still in contact with their roots and maintain their traditions and rituals, which are admired by contemporary people, myself included.
