 One example for populating a `TreeView` can be from a directory on the computer. You can create a `TreeView` in the `MainWindow.axaml` file in an Avalonia MVVM project.
 
 ```markup
-		<TreeView Items="{Binding Items}" 
-				  Width="400" Height="480" 
-				  HorizontalAlignment="Left" 
-			<TreeView.ItemTemplate>
-				<TreeDataTemplate ItemsSource="{Binding Subfolders}">
-					<TextBlock Text="{Binding strNodeText}"/>
-				</TreeDataTemplate>
-			</TreeView.ItemTemplate>
-		</TreeView>
+<TreeView Items="{Binding Items}" 
+	  Width="400" Height="480" 
+	  HorizontalAlignment="Left" 
+	<TreeView.ItemTemplate>
+		<TreeDataTemplate ItemsSource="{Binding Subfolders}">
+			<TextBlock Text="{Binding strNodeText}"/>
+		</TreeDataTemplate>
+	</TreeView.ItemTemplate>
+</TreeView>
 ```
 
 In the `MainWindowViewModel.cs` you can add this code which will recursively look up all the subfolders and populate the TreeView from `Items` and `Subfolders`
 
 ```markup
-    public class MainWindowViewModel : ViewModelBase
+public ObservableCollection<Node> Items { get; }
+public ObservableCollection<Node> SelectedItems { get; }
+public string strFolder { get; set; }
+
+public MainWindowViewModel()

+    strFolder = @"C:\Users\hooty\Desktop"; // EDIT THIS FOR AN EXISTING FOLDER
+
+    Items = new ObservableCollection<Node>();
+
+    Node rootNode = new Node(strFolder);
+    rootNode.Subfolders = GetSubfolders(strFolder);
+    
+    Items.Add(rootNode);
+}
+
+public ObservableCollection<Node> GetSubfolders(string strPath)
+{

     {
