 ## Features
 
 - 📷 Camera preview with multi-page capture (add pages one by one)
+- 🟢 Live edge-detection overlay while aiming — see the document outline before you capture
 - ✂️ Automatic edge detection + perspective correction (OpenCV), with manual corner adjustment
 - 🎨 Per-page filters: color, grayscale, black & white (document mode)
 - 🔄 Rotate, reorder and delete pages
 - 📄 Export to a multi-page PDF (A4 or original size)
 - ☁️ Direct upload to Paperless-ngx **or** share via the Android share sheet
+- ✅ Real upload feedback — the app waits for Paperless to consume the document and reports
+  **Added / Duplicate / Failed** (with a *Don't wait* option to skip the wait)
 - 🔊 Capture feedback: shutter sound (only when the ringer isn't silenced) + a brief flash
+- 🌍 Localized UI (see [Languages](#languages))
 - 🔐 API token stored encrypted (Android Keystore / EncryptedSharedPreferences)
 
 ## Tech
@@ -91,6 +95,16 @@ The build uses env vars, so nothing sensitive ends up in the repo.
 Prefer **https**; with `http://` the app warns that the token and documents travel over the
 network unencrypted.
 
+## Languages
+
+The UI ships in **English** (default), **Dutch**, **German**, **French**, **Spanish**,
+**Italian** and **Portuguese**. The app follows your device language automatically.
+
+All strings live in `app/src/main/res/values/strings.xml` (English base). Contributing a
+language is just adding a `values-<code>/strings.xml` with the same keys — e.g.
+`values-pl/strings.xml` for Polish. Every string must be present in every locale (the release
+lint enforces this).

 ## Roadmap
 
 Tracked as issues in the repository:
 
-- Live edge-detection overlay while aiming (like Microsoft Lens)
+- Batch import scans from the gallery (import existing photos as pages)
-- Internationalization: extract UI strings to resources + add translations
+- More UI languages (contributions welcome)
-- Batch import scans from the gallery
 
 > OCR is intentionally **not** done on-device: Paperless-ngx already runs OCR (via
 > OCRmyPDF/Tesseract) when it consumes the uploaded document.
