+
+## About
+
+This package adds distortion to the online audio stream, so it becomes like a radio receiver.
+
+You can change the signal level so that it can be very weak and there will be a lot of interference.
+
+The AudioContext Api is used. Therefore, it works only in the browser.
+
+[Example](https://analog-radio-example.web.app/)
 
 ## Install
 
 ```sh
 dart pub add analog_radio
 ```
 
+## Using
+
+```dart
+// Creating radio instance. Will be created audiocontext with audio processing.
+var radio = AnalogRadio();
+
+// Start playing sound. You will be able to hear the radio noise
+radio.turnOn();
+
+// You set up the "radio receiver" for a specific audio stream with a signal level of 0.9.
+// You will hear an audio stream with a slight addition of noise and distortion.
+radio.tune('https://vip2.fastcast4u.com/proxy/classicrockdoug?mp=/1', 0.9);
+
+// With a signal level of 0.3, the audio stream will be heard very poorly with a high level of interference
+radio.tune('https://vip2.fastcast4u.com/proxy/classicrockdoug?mp=/1', 0.3);
+
+// Stop playing sound
+radio.turnOff();
+```
+
 ## Developing
 
 ```sh
 dart pub global activate webdev
 dart pub get
-webdev serve
