+## Running Tests
+
+### In Godot Editor
+1. Open the project in Godot
+2. Go to **Tools → GUT → Run Tests**
+3. Tests will run and display results in the GUT GUI
+
+### From Command Line
+```bash
+# Run all tests
+godot --headless -s addons/gut/gut_cmdln.gd
+
+# Run specific test file
+godot --headless -s addons/gut/gut_cmdln.gd -d res://tests/test_admin_panel.gd
+
+# Export results to JUnit XML
+godot --headless -s addons/gut/gut_cmdln.gd -o test-results.xml

+
+## Test Statistics
+
+- **Total Test Files:** 38 (13 Done + 25 To Do)
+- **Total Tests:** 383 (133 Done + 250 To Do)
+- **Done Coverage Areas:** 
+  - Admin Panel, Shop/IAP, Authentication & Security
+  - Debug Cleanup, Sync/Desync, Deployment Pipeline
+  - Guest Identity, Mode Config, Backend Facades
+  - Versioning, Steam Depot, Tutorial Isolation
+- **To Do Coverage Areas:**
+  - Code Documentation, IAP Receipt Validation, Security Hardening
+  - Backend Service, Refactoring, Error Handling
+  - Analytics, Localization, Rate Limiting & Anti-Cheat
+  - Session Management, Testing Infrastructure, CI/CD
+  - Regional Servers, Identity Management, Economy Facade
+
+## Configuration
+
+Tests are configured in `gutconfig.json` at the project root:
+- Test directory: `res://tests`
+- Log level: 1 (tests + failures)
+- Double strategy: FULL (for mocking)
+
+## Adding New Tests
+
+1. Create a new file: `tests/test_feature_name.gd`
+2. Extend `GutTest`
+3. Add test methods starting with `test_`
+4. Run tests to verify
+
+Example:
+```gdscript
+extends GutTest
+
+func test_something():
+    assert_eq(1, 1, "Should pass")
+```
