Contributing Translations

Checkmate supports multiple languages. This guide explains how to contribute translations.

How to Add a New Language

1. Create a new JSON file in client/src/locales/ named with the language code (e.g., it.json for Italian)

2. Copy the structure from en.json and translate all values

3. Add the language to the language selector in the UI

Translation Guidelines

• en.json is the reference localization file, all keys should be declared here and mirrored in other localization files
• Translate only the values
• Use formal/informal tone consistently
• Test your translations in the UI

File Structure

client/src/locales/ ├── en.json # Source language ├── es.json # Spanish ├── de.json # German └── [lang].json # Your language

Testing Translations

1. Start the development server: npm run dev
2. Go to Settings → Language
3. Select your language
4. Verify all strings display correctly
