+BabySmash automatically uses your **keyboard language** for:
 
 1. **Text-to-speech voice** - Shapes and colors are spoken in your language
 2. **Shape/color names** - Translated to your locale (if available)
 3. **Word order** - "Red Circle" (English) vs "Círculo Vermelho" (Portuguese)
 
-**Supported locales:** English (en), Russian (ru), Portuguese (pt-BR, pt-PT)
-
-### Changing the Language
-
-1. Change your Windows keyboard language (Win+Space or taskbar language selector)
-2. BabySmash will use the matching TTS voice and translations
+**Supported locales:** English (en), German (de), Spanish (es), French (fr), Greek (el), Latvian (lv), Portuguese (pt-BR, pt-PT), Russian (ru)
 
 ### Adding a New Language
 
-Create a JSON file in `Resources/Strings/` named `{locale}.json` (e.g., `de-DE.json` for German):
+Create a JSON file in `Shared/Resources/Strings/` named `{locale}.json` (e.g., `ja-JP.json` for Japanese):
 
 ```json
 {
   "ColorShapeFormat": "{0} {1}",
-  "Circle": "Kreis",
-  "Red": "Rot",
+  "Circle": "丸",
+  "Red": "赤",
   ...
 }
 ```
 
 - Use `"{0} {1}"` for color-first languages (English: "Red Circle")
 - Use `"{1} {0}"` for shape-first languages (Portuguese: "Círculo Vermelho")
 
-**Note:** You may need to install the TTS voice for your language in Windows Settings → Time & Language → Speech.
