First the following software needs to be installed:

`pip3 install jupyterlab notebook`

First copy the service file template:

`sudo cp templates/jupyterlab@.service /etc/systemd/system`

And the lab.conf nginx configuration file:

`sudo mkdir /etc/nginx/includes`
`sudo cp templates/lab.conf /etc/nginx/includes/`

Now 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

This service file is a template for all the jupyter lab services that are running, which is one for each user. 

Now add the generated nginx configurations for each jupyterlab instance:

`cat users.nginx.conf`
`sudo nano /etc/nginx/sites-available/default`

And convert the markdown into HTML to add links to the index page: 

`pandoc users.md -o users.html`

Now try to start one jupyterlab instance with:

`sudo systemctl start jupyter@murtaugh`
