Need help with Korean translation

[iluwatar]

To show the principles correctly on the Korean website, we need a translation. README.md should contain the English version and the Korean translation could be placed to localization/ko/README.md

Acceptance criteria

• README.md translated to Korean and stored in localization/ko/README.md
