+# Stac Logger
+
+A lightweight and reusable logging utility for the Stac framework. It switches between implementations—using Flutter's debugPrint on web/WASM platforms and the robust logger package on native platforms—ensuring optimal performance and compatibility across all environments.
+
+## Getting started
+
+Add the package to your `pubspec.yaml`:
+
+```yaml
+dependencies:
+  stac_logger: ^1.0.0
+```
+
+Then run:
+
+```bash
+flutter pub get
+```
+
+## Usage
+
+Import the package and use the `Log` class to log messages:
+
+```dart
+import 'package:stac_logger/stac_logger.dart';
+
+void main() {
+  // Log a debug message
+  Log.d('Debug message');
+
+  // Log an info message
+  Log.i('Info message');
+
+  // Log a warning message
+  Log.w('Warning message');
+
+  // Log an error message
+  Log.e('Error message');
+}
+```
+
+## Implementation Details
+
+This package uses conditional imports to select the appropriate logging implementation based on the platform:
+
+- On native platforms (iOS, Android, desktop), it uses a full-featured logger implementation
+- On web/WASM platforms, it uses a simplified implementation compatible with those environments
+
+The conditional import approach ensures that no `dart:io` code is included in web/WASM builds, making the package fully compatible with WebAssembly.
+
+## Additional information
+
+This package is part of the Stac framework ecosystem and is designed to provide logging functionality that works across all platforms, including WASM environments
