Julia’s official documentation is in English, but many groups work to translate and localize documentation and other resources. The following is a list of past localization efforts that may not be active anymore.
JuliaCN (Chinese)
JuliaTokyo (Japanese)
JuliaEs (Spanish)
JuliaLangPt (Portuguese)
JuliaKorea (Korean)
JuliaGerman (German)
Julia Francophonie (French)

Please provide a PR to add other localization efforts.
