In Mexico the Regular Grand Lodges of the United States of Mexico Confederation (Confederación de Grandes Logias Regulares de la República Mexicana) assigned the Mexican Valley Grand Lodge (Gran Logia "Valle de México") to adapt the ritual for the Mexican youth; but in 1991 the United Mexican Grand Lodge of Veracruz (Gran Logia Unida Mexicana) created the "Vademécum del AJEF", the first compilation of ceremonials and the AJEF Theory - symbols and philosophic principles. Because of that it is the basis for the subsequent documents elaborated by other Grand Lodges, as the "Prontuario del AJEF", created in 1994 by the Grand Lodge Valle de México.
