+
+## 🚀 Features
+
+- 🔍 Find all `TMP_Localizer` components in project prefabs
+- ✏️ Edit `localizationKey` values directly in the Editor window
+- 📅 Save changes back into `.txt` files and update prefab assets
+- ➕ Automatically add `TMP_Localizer` to all `TMP_Text` components
+- 🌍 Generate new language files based on any existing base language

+
+## 📆 Requirements
+
+- Unity 2022.3+
+- TextMeshPro
+- [Odin Inspector](https://odininspector.com/) (Editor-only, for UI rendering)
+
+---
+
+## 🛠️ How To Use
+
+1. Open the editor via `Tools > Localization Editor 🇨`
+2. Select a language from the dropdown
+3. Search or scroll to find any localization key
+4. Use `Find All TMP_Localizers in Resources` to scan all prefabs
+5. Edit keys and press `Save Changes To Assets` to apply
+6. Use `Add TMP_Localizer to All TMP_Text In Resources` to automate component attachment
+7. Generate new language files with the `Create New Language From Base` section
+
+---
+
+## 📚 Project Structure
+
+- `LocalizationEditorWindow.cs` — the main Odin-powered editor window
+- `Resources/Localization/*.txt` — language files
+- `TMP_Localizer.cs` — the component that applies localized text to `TMP_Text`
+
+---
+
+## 🔹 Usage Example
+
+Add a `TMP_Localizer` to any `TMP_Text` element. Set its `localizationKey`.
+On language change, it will update the text automatically.
+
+```csharp
+public class TMP_Localizer : LocalizeBase
+{
+    public override void UpdateLocale()
+    {
+        _text.text = Locale.GetLocalized(localizationKey);
+    }
+}
+```
