I hope to note that there is no Netlify preview for this branch (dev-ko) yet.

@seokho-son, just to clarify, this is to create the Korean branch and that's why you need one of us to approve as well, correct?

@CathPag

this is to create the Korean branch .. ?

I created Korean branch https://github.com/cncf/glossary/tree/dev-ko already. This PR is not about creating a new branch but is to config Korean language to enable Korean option to the glossary website. The configuration will be effective only in dev-ko.

I assume this kind of PR is the first PR that each localization team open firstly.

that's why you need one of us to approve as well, correct?

Each localization team needs to modify config.toml for a new language configuration according to https://github.com/cncf/glossary/blob/main/LOCALIZATION.md#add-a-new-language-setting-to-site-configuration

Even though the target branch of this PR is dev-ko, config.toml needs to be properly modified since config.toml will be merged to main branch eventually.
So, maintainers would better to check config.toml is configured properly to help localization teams. :)

[FYI] I added Korean approvers for files in /contents/ko/ to CODEOWNERS. https://github.com/cncf/glossary/blob/dev-ko/CODEOWNERS#L11
But it seems not work yet since permission setting for dev-ko branch is not appropriate yet.
(I guess PR #293 will resolve this problem)

Ok, since you would like a maintainer to review for correctness, let's wait for Jason to come back next week as I can only really review and approve content, not setups.

Seems good but obviously I don't understand Korean. I'm not sure why the _index.md files are in English but I'm happy to trust your judgement.

[seokho-son]

@JasonMorgan Thanks :)
I just wanted to show basic files that need to be included in a new language configuration to maintainers and new l10n teams. obviously not for requesting Korean review ;)

In case of content/ko/_index.md, the contents in the file is Korean.
File name should be same with the file in English directory (content/en/_index.md).
Then Hugo understands it is a localized document.
