How to contribute translations
You can translate cobalt to any language you want on cobalt's Crowdin. Feel free to ignore QA errors if you think you know better. If you don't see a language you want to translate cobalt to, open an issue, and I'll add it to Crowdin.
Translation guidelines:
- All text is ALWAYS stylized as lowercase unless it's STRESSED LIKE THIS or is an internal value like
{ContactLink}or{appName}.- Example: "
this is a live video, i am yet to learn how to look into future. wait for the stream to finish and try again!".
Notice how everything is lowercase, no matter the punctuation marks? Yes, that's cobalt's style and you have to follow it.
- Example: "
- Avoid formal language. Leave it for big and classy tech companies. Use informal language wherever possible.
- Keep translations lively, friendly, and fun. Translate strings as if the user was your buddy.
- You can (and should) rephrase sentences as long as they keep the same sense and send the same message as original.
- You can add wordplays or puns if it feels natural to do so.
- Do NOT use offensive or explicit vocabulary.
- Check if there are issues in UI with your localization, and optimize it accordingly. If impossible, open an issue.
- Be nice.
