+## Notes
+
+If you need to change something about the environment of the user on
+the remote host (for example, the user has been added to a new unix
+group) you need to restart the vscode server that runs on the remote
+host. Do this in vscode:
+
+ctrl+shift+p: `Remote-SSH: Kill VS Code Server on Host`
+
+This is because the vscode server remains running on the remote host
+even after you disconnect, so exiting/restarting vscode on the desktop
+has no effect.
