There will be ongoing translation work available to keep all the translations of the Language Reference synced with the English version as we work to improve it. I believe they're working on a system to automatically generate issue reports in all the translation repositories whenever they go out of sync with reference-en but I don't know if that system is in place yet. So if you're interested in continuing with the project you might want to use GitHub's "Watch" feature on the reference-ko and/or reference-en repositories so that you will get a notification when that happens.
