+- Ability to hide code cells when rendering Jupyter notebooks. 
+
+After setting up Connect 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 \
+    --hide-all-input \
+    hello_world.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 \
+    --hide-tagged-input \

+### Hide Jupyter Notebook Input Code Cells
+
+The user can render a Jupyter notebook without its corresponding input code cells by passing the '--hide-all-input' flag through the cli:
+
+```
+rsconnect deploy notebook \
+    --server https://connect.example.org:3939 \
+    --api-key my-api-key \
+    --hide-all-input \
+    my-notebook.ipynb
+```
+
+To selectively hide input cells in a Jupyter notebook, the user needs to follow a two step process:
+1. tag cells with the 'hide_input' tag, 
+2. then pass the ' --hide-tagged-input' flag through the cli:
+
+```
+rsconnect deploy notebook \
+    --server https://connect.example.org:3939 \
+    --api-key my-api-key \
+    --hide-tagged-input \
+    my-notebook.ipynb
+```
+
+By default, rsconnect-python does not install Jupyter notebook related depenencies. These dependencies are installed via rsconnect-jupyter. When the user is using the hide input features in rsconnect-python by itself without rsconnect-jupyter, he/she needs to install the following package depenecies:
