 ## Configuring a Service
 
-TBD
+Services help generate and run bash scripts on nodes for a given purpose.
+
+Configuring the files of a service results in a specific hard coded script being
+generated, instead of the default scripts, that may leverage dynamic generation.
+
+Editing service properties:
+```python
+# configure a service, for a node, for a given session
+# modify any of the following features
+# the files and the names that will be generated
+# the directories that will be mounted unique to the node
+# startup commands to run
+# validation commands to run
+# shutdown commands to run
+core.set_node_service(
+    session_id,
+    node_id,
+    service_name,
+    files=["file1.sh", "file2.sh"],
+    directories=["/etc/node"],
+    startup=["bash file1.sh"],
+    validate=[],
+    shutdown=[],
+)
+```
+
+Editing a service file:
+```python
+# to edit the contents of a generated file you can specify
+# the service, the file name, and its contents
+# the file name must map to one of the files the service
+# supports by default or one added from a command above
+core.set_node_service_file(
+    session_id,
+    node_id,
+    service_name,
+    file_name,
+    "echo hello",
+)
+```
 
 ## File Examples
 
-File versions of these examples can be found
+File versions of the network examples can be found
 [here](https://github.com/coreemu/core/tree/master/daemon/examples/grpc).
 These examples will create a session using the gRPC API when the core-daemon is running.
