This year, Wikipedia in Spanish reached one million articles and released a basic user guide in Guaraní. The idea is to revive the Guaraní-speaking community in this great platform. So far there are only 20 articles in that language.
If you are interested in collaborating with this project, download the wikipedia in Guaraní guide and join the community Vikipetã !
