Multilingual Go Book Project
A project, active since December 2018, to translate the free introductory book A Go Guide From a Beginner into different languages.
A Go Guide From a Beginner was initially written by Charalampos Kapolos in English, taking up 192 pages, and was then translated into the author's native language, Greek. It has been fully translated into French and Spanish, and partially into Brazilian Portugese, Russian, Serbian and German.
