## What's cobalt?
|
|
cobalt is a social media downloader with zero bullshit. It's friendly, efficient, and doesn't bother you with shock ads or privacy invasion "consent" popups.
|
|
|
|
It tries to preserve original media quality, and in most cases you get best quality possible (you can set your preferences in settings).

## cobalt API
|
|
cobalt has an open API that you can use for free. It's pretty straightforward to use, [check out the docs](https://github.com/wukko/cobalt/blob/current/docs/API.md) and see for yourself.
|
|
|
|
## How to contribute translations
|
|
You can translate cobalt to any language you want on [cobalt's crowdin](https://crowdin-co.wukko.me/). 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:
|
|
- Avoid formal language. Leave it for big and classy tech companies. Use informal language wherever possible.
|
|
- Strings are **ALWAYS** stylized as lowercase unless it's STRESSED LIKE THIS or is an internal value like `{ContactLink}`.
|
|
- Keep translations lively, friendly, and fun. Translate strings as if the user was your buddy.
|
|
- Automatic translations from original language are not valid, and will be ignored.
|
|
- You can (and should) rephrase sentences as long as they keep the same point, if you think it'd be better that way.
|
|
- You can add wordplays or puns if it feels natural to do so.
|
|
- Even though I love cursing, keep that to minimum in translations, and do **NOT** use any offensive words.
|
|
- Check if there are issues in UI with your localization, and optimize it accordingly, or open an issue.
|
|
- Add "(in english)" translated to your language at the end of `ChangelogLastCommit`, `ChangelogLastMajor`, and `ChangelogOlder`. Those are always kept exclusively in English (for now), due to how often changelog changes.
|
|
- Sample translation to Russian: `"ChangelogLastCommit": "последний коммит (на английском)"`
|
|
- Be nice.
|
|
