+After setting up Connect (>=1.9.0) and rsconnect-python, the user can render a Jupyter notebook without its corresponding code cells by passing the ' hide-all-input' flag through the rsconnect cli:
 
 ```
 rsconnect deploy notebook \
-    -n server \
-    -k APIKey \
+    --server https://connect.example.org:3939 \
+    --api-key my-api-key \
     --hide-all-input \
-    hello_world.ipynb
+    mynotebook.ipynb
 ```
 
 To selectively hide the input of cells, the user can add a tag call 'hide_input' to the cell, then pass the ' hide-tagged-input' flag through the rsconnect cli:
 
 ```
 rsconnect deploy notebook \
-    -n server \
-    -k APIKey \
+    --server https://connect.example.org:3939 \
+    --api-key my-api-key \
     --hide-tagged-input \
