+## How to release
+
+If you create a new instance like CBCentralManager, CBMutableService with using "new" keyword,
+you must call Dispose() method when you don't need it anymore.
+
+```csharp
+CBCentralManager _centralManager;
+
+...
+
+void OnDestroy()
+{
+    if (_centralManager != null)
+    {
+        _centralManager.Dispose();
+        _centralManager = null;
+    }
+}
+```
