## What's cobalt?
cobalt is social media downloader with zero bullshit. It's friendly, efficient, works on anything with a browser, and doesn't bother you with porn ads or privacy invasion "consent" popups.

It preserves original media quality so you get best downloads possible (unless you change that in settings).

## How to contribute translations
You can translate cobalt to any language you want on [cobalt's crowdin](https://crowdin.com/project/cobalt). 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 boring big tech companies. Use informal language on all occasions.
- 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 cobalt 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` and `ChangelogLastMajor`. Those are always kept exclusively in English, due to how often changelog changes.
    - Example of translation to Russian: `"ChangelogLastCommit": "последний коммит (на английском)"`
- Be nice.

Setup script installs all needed `npm` dependencies, but you have to install `Node.js` and `git` yourself.
