 To add a new jurisdiction to the repository:
 
 1. **Create jurisdiction subdirectory** in the [TransLegal/grading-answers](https://huggingface.co/datasets/TransLegal/grading-answers) repository:
-   - Use format: `{language-code}-{country-code}` (e.g., `sv-se`, `fr-fr`, `es-es`)
-   - Example: Create `sv-se/` directory
+   - **Format:** `{language-code}-{country-code}` following ISO standards:
+     - Language code: ISO 639-1 (2-letter lowercase, e.g., `hr`, `en`, `sv`)
+     - Country code: ISO 3166-1 alpha-2 (2-letter lowercase, e.g., `hr`, `us`, `se`)
+     - Combined format: lowercase language code, hyphen, lowercase country code (e.g., `hr-hr`, `en-us`, `sv-se`)
+   - The app automatically converts these codes to display names (e.g., "Croatian-Croatia", "English-United States", "Swedish-Sweden")
+   - Example: Create `sv-se/` directory for Swedish-Sweden
 
 2. **Add grading template file:**
    - Upload `grading_template.parquet` to `{jurisdiction}/grading_template.parquet`
