-We use the make_user_accounts.py script with the following scripts:
+First jupyterlab needs to be installed:
+
+`pip3 install jupyterlab`
+
+You can use the make_user_accounts.py script with the following scripts:
 
 * `--passwords`: words.txt -- a txt file with ingredient words on each line to generate passwords with
 * `--from_file`: users.txt -- a txt file with a username on each line
 * `--servername`: sandbol -- a string
+
+The script generates:
+
+* `users.csv`: a list of all the users, their personal ports, their passwords
+* `users.md`: a bulletpoint list with a link to the `/__LAB__/` link for each user  
+* `users.nginx.conf`: snippets of nginx configuration that can be added to the main nginx config file
+
+Then the service file template is copied:
+
+`sudo cp templates/jupyterlab@.service /etc/systemd/system`
+
+This service file is a template for all the jupyter lab services that are running, which is one for each user. 
+
+Now try to start one jupyterlab instance with:
+
+`sudo systemctl start jupyter@murtaugh`
