Hi @jaehanbyun, thanks for the PR! If you don't mind I'll get back to this PR shortly. We are currently in the process of looking at using an integration for translations which will be an improvement over the current set up. :)

Hi @jaehanbyun, to provide you an update here. We have integrated a new tool (Locadex agent) into our repo which ensures that translated sites are continuously translated with every commit to the English docs. We're discussing internally now, but I hope we can roll out Korean docs in the next few weeks.

@Blargian Oh, I’m really looking forward to it, the tool looks great. Thanks for letting me know.
