+- `DocumentStates.Corrected` - Document has been reviewed and corrected
+- `DocumentStates.Uncorrected` - Document needs correction
+
+### Example: Signing and Approving Documents
+
+```csharp
+private void SignAndCloseButton_Click(object sender, RoutedEventArgs e)
+{
+    // Sign report -> set document state to Corrected
+    _documentState = DocumentStates.Corrected;
+    Close();
+}
+```
+
+### Closing Documents with State
+
+```csharp
+// Close with document ID and state
+_vuiController.Close(_documentId.Text, _documentState);
+```

+## Summary
