+# Translation Guide
+
+Super Productivity uses JSON files for translations, located in `src/assets/i18n/`.
+
+## How to Contribute
+
+1. Find your language file in `src/assets/i18n/` (e.g., `de.json` for German)
+2. Edit the JSON file directly
+3. Submit a pull request
+
+## Important Notes
+
+### Fallback Language
+
+**English (`en.json`) is the fallback language.** If a translation is missing or empty, the app automatically displays the English text.
+
+### Empty Values Are Intentional
+
+When you see empty strings (`""`), this is **intentional** - it triggers the English fallback. Do not copy the English text into empty fields unless you're providing an actual translation.
+
+```json
+{
+  "SOME_KEY": ""
+}
+```
+
+The above will display the English text for `SOME_KEY`.
+
+### File Format
+
+- Nested JSON structure
+- Keys use SCREAMING_SNAKE_CASE
+- Keep the structure intact - only change the string values
+
+### Example
+
+```json
+{
+  "G": {
+    "CANCEL": "Abbrechen",
+    "SAVE": "Speichern"
+  }
+}
+```
+
+## Tips
+
+- Use `en.json` as reference for context
+- Keep translations concise (UI space is limited)
+- Test your translations locally if possible (`ng serve`)
