## Adding a New Translation

### Method 1: Using Poedit (Recommended)

1. Download and install [Poedit](https://poedit.net/)
2. Open Poedit and click "Create new translation"
3. Select the `wc-tier-package-prices.pot` file
4. Choose your language
5. Translate all strings
6. Save the file (this creates both `.po` and `.mo` files automatically)
7. Name the files as `wc-tier-package-prices-{locale}.po` and `wc-tier-package-prices-{locale}.mo`
   - Example for French: `wc-tier-package-prices-fr_FR.po` and `wc-tier-package-prices-fr_FR.mo`

### Method 2: Using Command Line

1. Copy the POT file to create a new PO file:
   ```bash
   cp wc-tier-package-prices.pot wc-tier-package-prices-fr_FR.po
   ```

2. Edit the PO file header:
   ```
   "Language: fr_FR\n"
   "Language-Team: French\n"
   "Plural-Forms: nplurals=2; plural=(n > 1);\n"
   ```

3. Translate all `msgstr` entries in the PO file

4. Compile the PO file to MO:
   ```bash
   msgfmt -o wc-tier-package-prices-fr_FR.mo wc-tier-package-prices-fr_FR.po
   ```

## Command Line Compilation

If you prefer command-line tools:

```bash
# Compile a single language
msgfmt -o wc-tier-package-prices-de_DE.mo wc-tier-package-prices-de_DE.po

# Compile all languages at once
for po in *.po; do
    msgfmt -o "${po%.po}.mo" "$po"
done

# Verify MO file
msgunfmt wc-tier-package-prices-de_DE.mo | less
```

## Translation Guidelines

### Style Guide

1. **Consistency**: Use consistent terminology throughout
2. **Context**: Consider the context where text appears (admin vs frontend)
3. **Length**: Keep translations similar in length to the original
4. **Formality**: Maintain appropriate level of formality for your language
5. **Technical Terms**: Don't translate technical terms like "WooCommerce"

### German Translation Notes

- Uses formal "Sie" form (not informal "du")
- Currency examples adjusted (€ instead of $)
- Decimal separator uses comma (9,99 instead of 9.99)
- Date format: DD.MM.YYYY

### Best Practices

- ✅ Translate user-facing strings
- ✅ Keep HTML tags intact
- ✅ Preserve placeholders like `%s`, `%d`
- ✅ Maintain the same number of placeholders
- ❌ Don't translate variable names
- ❌ Don't translate code or CSS classes
- ❌ Don't remove or add HTML tags
