-####There are 2 ways you can work with this component:
+## API
 
-* Set raw byte array asynchronously 
+Set raw byte array asynchronously 
 
 ```java
 
     // does downsampling in O(N) and shows the animation you see in a gif above (the inflation-like one)
     setRawData(byte[] data);
 
     // you also have the ability to listen, when does the downsampling complete
-    setRawData(byte[] data, Function0<Unit> callback);
+    setRawData(byte[] data, OnSamplingListener callback);
 ```
 
-* In case you have scaled byte array you want to draw
+In case you have scaled byte array you want to draw
 
 ```java
 
     // instantly redraws the wave without async downsampling process
     setScaledData(byte[] scaledData);
 ```
 
+Now you can use it like a `Seekbar`, it reacts on touches, just attach listener
+
+```java
+    setOnProgressListener(OnProgressListener listener);
+```
+
+This listener has 3 methods like a built-in `Seekbar`
+
+```java
+	void onStartTracking(float progress) {
+		// invokes when user touches the view
+   	}
+
+   	void onStopTracking(float progress) {
+		// invokes when user releases the touch
+   	}
+
+   	void onProgressChanged(float progress, boolean byUser) {
+		// invokes every time the progress's been changed
+   	}
+```

 ## Contribution
 
 There are some features(like seeking) I am about to implement, but a little bit later.
