+# Internationalization (I18N)
+
+This guide explains the multi-language support system in CrossPoint Reader.
+
+## Supported Languages (Updating)
+
+
+---
+
+
+## For Developers
+
+### Translation System Architecture
+
+The I18N system uses **per-language YAML files** to maintain translations and a Python script to generate C++ code:
+
+```
+lib/I18n/
+├── translations/                # One YAML file per language
+│   ├── english.yaml
+│   ├── spanish.yaml
+│   ├── french.yaml
+│   └── ...
+├── I18n.h
+├── I18n.cpp
+├── I18nKeys.h                   # Enums (auto-generated)
+├── I18nStrings.h                # String array declarations (auto-generated)
+└── I18nStrings.cpp              # String array definitions (auto-generated)
+
+scripts/
+└── gen_i18n.py                  # Code generator script
+```
+
+**Key principle:** All translations are managed in the YAML files under `lib/I18n/translations/`. The Python script generates the necessary C++ code automatically.
+
+---
+
+### YAML File Format
+
+Each language has its own file in `lib/I18n/translations/` (e.g. `spanish.yaml`).
+
+A file looks like this:
+
+```yaml
+_language_name: "Español"
+_language_code: "SPANISH"
+_order: "1"
+
+STR_CROSSPOINT: "CrossPoint"
+STR_BOOTING: "BOOTING"
+STR_BROWSE_FILES: "Buscar archivos"
+```
+
+**Metadata keys** (prefixed with `_`):
+- `_language_name` — Native display name shown to the user (e.g. "Français")
+- `_language_code` — C++ enum name (e.g. "FRENCH"). Must be a valid C++ identifier.
+- `_order` — Controls the position in the Language enum (English is always 0)
+
+**Rules:**
+- Use UTF-8 encoding
+- Every line must follow the format: `KEY: "value"`
+- Keys must be valid C++ identifiers (uppercase, strats with STR_)
+- Keys must be unique within a file
+- String values must be quoted
+- Use `\n` for newlines, `\\` for literal backslashes, `\"` for literal quotes inside values
+
+---
+
+### Adding New Strings
+
+To add a new translatable string:
+
+#### 1. Edit the English YAML file
+
+Add the key to `lib/I18n/translations/english.yaml`:
+
+```yaml
+STR_MY_NEW_STRING: "My New String"
+```
+
+Then add translations in each language file. If a key is missing from a
+language file, the generator will automatically use the English text as a
+fallback (and print a warning).
+
+#### 2. Run the generator script
+
+```bash
+python3 scripts/gen_i18n.py lib/I18n/translations lib/I18n/
+```
+
+This automatically:
+- Fills missing translations from English
+- Updates the `StrId` enum in `I18nKeys.h`
+- Regenerates all language arrays in `I18nStrings.cpp`
+
+#### 3. Use in code
+
+```cpp
+#include <I18n.h>
+
+// Using the tr() macro (recommended)
+renderer.drawText(font, x, y, tr(STR_MY_NEW_STRING));
+
+// Using I18N.get() directly
+const char* text = I18N.get(StrId::STR_MY_NEW_STRING);
+```
+
+**That's it!** No manual array synchronization needed.
+
+---
+
+### Adding a New Language
+
+To add support for a new language (e.g., Italian):
+
+#### 1. Create a new YAML file
+
+Create `lib/I18n/translations/italian.yaml`:
+
+```yaml
+_language_name: "Italiano"
+_language_code: "ITALIAN"
+_order: "7"
+
+STR_CROSSPOINT: "CrossPoint"
+STR_BOOTING: "AVVIO"
+```
+
+You only need to include the strings you have translations for. Missing
+keys will fall back to English automatically.
+
+#### 2. Run the generator
+
+```bash
+python3 scripts/gen_i18n.py lib/I18n/translations lib/I18n/
+```
+
+This automatically updates all necessary code.
+
+---
+
+### Modifying Existing Translations
+
+Simply edit the relevant YAML file and regenerate:
+
+```bash
+python3 scripts/gen_i18n.py lib/I18n/translations lib/I18n/
+```
+
+---
+
+### UTF-8 Encoding
+
+The YAML files use UTF-8 encoding. Special characters are automatically converted to C++ UTF-8 hex sequences by the generator.
+
+---
+
+### I18N API Reference
+
+```cpp
+// === Convenience Macros (Recommended) ===
+
+// tr(id) - Get translated string without StrId:: prefix
+const char* text = tr(STR_SETTINGS_TITLE);
+renderer.drawText(font, x, y, tr(STR_BROWSE_FILES));
+Serial.printf("Status: %s\n", tr(STR_CONNECTED));
+
+// I18N - Shorthand for I18n::getInstance()
+I18N.setLanguage(Language::SPANISH);
+Language lang = I18N.getLanguage();
+
+// === Full API ===
+
+// Get the singleton instance
+I18n& instance = I18n::getInstance();
+
+// Get translated string (three equivalent ways)
+const char* text = tr(STR_SETTINGS_TITLE);              // Macro (recommended)
+const char* text = I18N.get(StrId::STR_SETTINGS_TITLE);   // Direct call
+const char* text = I18N[StrId::STR_SETTINGS_TITLE];       // Operator overload
+
+// Set language
+I18N.setLanguage(Language::SPANISH);
+
+// Get current language
+Language lang = I18N.getLanguage();
+
+// Save language setting to file
+I18N.saveSettings();
+
+// Load language setting from file
+I18N.loadSettings();
+
+// Get character set for font subsetting (static method)
+const char* chars = I18n::getCharacterSet(Language::FRENCH);
+```
+
+---
+
+## File Storage
+
+Language settings are stored in:
+```
+/.crosspoint/language.bin
+```
+
+This file contains:
+- Version byte
+- Current language selection (1 byte)
+
+---
+
+## Translation Workflow
+
+### For Developers (Adding Features)
+
+1. Add new strings to `lib/I18n/translations/english.yaml`
+2. Run `python3 scripts/gen_i18n.py lib/I18n/translations lib/I18n/`
+3. Use the new `StrId` in your code
+4. Request translations from translators
+
+### For Translators
+
+1. Open the YAML file for your language in `lib/I18n/translations/`
+2. Add or update translations using the format `STR_KEY: "translated text"`
+3. Keep translations concise (E-ink space constraints)
+4. Make sure the file is in UTF-8 encoding
+5. Run `python3 scripts/gen_i18n.py lib/I18n/translations lib/I18n/` to verify
+6. Test on device or submit for review
