+# Visualizations on a remote machine
+# If you are running this notebook on a remote machine, we need to set up a few things so that you can view `napari` on the remote machine.
+# 1. From VSCode connected to your remote machine, forward a port (e.g. `4000`) to your local machine.
+#     - Open you command palette in VSCode (usually CMD-Shift-P) and type "forward a port"
+#     - Then type in the desired port number `4000` and hit enter
+#     - From the "PORTS" tab, you should see port 4000 listed as a forwarded port
+# 2. Download and install [NoMachine](https://www.nomachine.com/download) on your local machine if it is not already installed.
+# 3. Enter the server address in host, set the port to match the port you forwarded in step 1 and protocol as NX. Feel free to enter any name you would like.
+# 4. Click on the configuration tab on the left.
+# 5. Choose "Use key-based authentication with a key you provide" and hit the "Modify" button.
+# 6. Provide the path to your ssh key .pem file.
+# 7. Finally hit connect (or Add).
+# 8. If you are asked to create a desktop, click yes.
+# 9. You should then see a time and date, hitting enter should let you enter your username and access the desktop. The first login may be slow.
+# 10. Still in NoMachine, open a shell window. Hit the application button in the bottom left corner and launch "Konsole"
+# 11. From the shell, run `echo $DISPLAY`. Copy the output. It should be something like `:1005`
+# 12. Return to your notebook in VSCode, and proceed with the exercise.
+# 13. Modify the cell below to input the DISPLAY port you retrieved in step 11

+import os
+os.environ["DISPLAY"] = "TODO"
