+# Tree (Data Structure)
+![status](https://img.shields.io/badge/status-WorkInProgress-red)
+[![License: MIT](https://img.shields.io/badge/License-MIT-blue.svg)](https://github.com/AdrianKuta/Design-Patterns-Kotlin/blob/master/LICENSE)
+
+Simple implementation to store object in tree structure. Method `toString()` is overrided to provide nice tree view in logs.
+
+## Usage
+
+```kotlin
+val root = TreeNode<String>("Root")
+val beveragesNode = TreeNode<String>("Beverages")
+val curdNode = TreeNode<String>("Curd")
+root.addChild(beveragesNode)
+root.addChild(curdNode)
+
+val teaNode = TreeNode<String>("tea")
+val coffeeNode = TreeNode<String>("coffee")
+val milkShakeNode = TreeNode<String>("Milk Shake")
+beveragesNode.addChild(teaNode)
+beveragesNode.addChild(coffeeNode)
+beveragesNode.addChild(milkShakeNode)
+
+val gingerTeaNode = TreeNode<String>("ginger tea")
+val normalTeaNode = TreeNode<String>("normal tea")
+teaNode.addChild(gingerTeaNode)
+teaNode.addChild(normalTeaNode)
+
+val yogurtNode = TreeNode<String>("yogurt")
+val lassiNode = TreeNode<String>("lassi")
+curdNode.addChild(yogurtNode)
+curdNode.addChild(lassiNode)
+
+println(root)
+System.out.println("Remove: ${curdNode.value}")
+root.removeChild(curdNode)
+System.out.println("Remove: ${gingerTeaNode.value}")
+root.removeChild(gingerTeaNode)
+println(root)
+```
