Originally, this article, published on January 16, 2023, was titled "Nchia Tunchjianxi Kakje: Practices of community outreach at the Intercultural University of the State of Puebla, San Marcos Tlacoyalco". However, under our responsibility as authors, the title was changed to "Xra nche'e ni kunixin rajna: Prácticas de vinculación comunitaria en la Universidad Intercultural del estado de Puebla, San Marcos Tlacoyalco" in order to state more clearly the explanatory intentions of the argument of our article. We also express our gratitude to the student in Language and Culture at the Intercultural University of the State of Puebla (UIEP) in Tlacotepec, Anahy Hernández Juárez (2023), who has translated the concept of "Vinculación comunitaria (Xra nche'e ni kunixin rajna)" into the Ngigua language in its variant of San Marcos Tlacoyalco, and which reliably expresses this explanatory character of the dialogue of knowledge with which we have expressed our theoretical-methodological and ethical-political position in this publication. Likewise, we thank the editor of Mirada Antropológica for making this correction out of time.
