 ### Integrations
 
 To get the XML from shading network name:
-```
+```python
 import maya2katana
 reload (maya2katana)
 node_name = 'materialSG'
+# Get the xml as string
 resulting_xml = maya2katana.generate_xml(node_name)
 ```
+
+You can save the resulting XML to file and bring it into Katana:
+
+```python
+# Now create the Katana shading network
+# Suppose the XML (string) is already loaded
+# to 'resulting_xml' string variable
+from Katana import NodegraphAPI, KatanaFile
+# Create a group for shading network
+group_node = NodegraphAPI.CreateNode(node_name, NodegraphAPI.GetRootNode())
+# Bring the nodes to Katana scene
+# and place them inside the newly created group
+nodes = KatanaFile.Paste(resulting_xml, group_node)
+```
