The Polkadot-JS UI has been translated into several languages, including French, Spanish, Italian, Korean, and more. You can change the language settings under “Default browser language” here.

If you are interested in contributing to translating Polkadot documents into your language, keep an eye on Crowdin (translation rewarded in tips) and Github (bounties paid in Dai), or join the Ambassador program.

We also have our Thousand Contributor's Programme where you can be rewarded for contributions to translations.
