+# Roggle
 
-Simple, colorful and easy to expand logger for dart.
+Simple, colorful and easy to expand logger for dart.<br>
+Inspired by [logger](https://pub.dev/packages/logger).
 
-## Features
+## Getting Started
 
-TODO: List what your package can do. Maybe include images, gifs, or videos.
+Just create an instance of `Roggle` and start logging:
 
-## Getting started
+```dart
+final logger = Roggle();
+
+logger.d('Roggle is working!');
+```
+
+Instead of a string message, you can also pass other objects like `List`, `Map`, `Set` or `Function`.
+
+## Output
+
+![Roggle](https://user-images.githubusercontent.com/13707135/166134270-a2c6316f-eff1-4533-9022-eb4e6cee0697.png)
 
-TODO: List prerequisites and provide or point to information on how to
-start using the package.
+# Documentation
 
-## Usage
+Roggle's API is almost the same as logger. See [logger](https://pub.dev/packages/logger) for basic usage.
 
-TODO: Include short and useful examples for package users. Add longer examples
-to `/example` folder. 
+## Options
+
+If you use the `SinglePrettyPrinter`, there are more options:
 
 ```dart
-const like = 'sample';
+final logger = Roggle(
+  printer: SinglePrettyPrinter(
+    loggerName: '[APP]', // Print a logger name for each log message
+    colors: true, // Colorful log messages
+    printCaller: true, // Print a caller for each log message
+    printEmojis: true, // Print an emoji for each log message
+    printLabels: true, // Print a level string for each log message
+    printTime: true, // Print a timestamp for each log message
+    stackTraceLevel: Level.error, // The current logging level to display stack trace
+    stackTraceMethodCount: 10, // Number of stack trace methods to display
+  ),
+);
+```
