 ### For a fresh deploy
 - Copy `devops/tracker-nginx.conf` into `/etc/nginx/sites-enabled/`. Probably restart nginx (`sudo systemctl restart nginx`)
 - Copy `devops/tracker-supervisor.conf` into `/etc/supervisor/conf.d/`
-- Run `pipenv install`
+- Run `poetry install`
 - Run `npm run build`
 - Run `sudo supervisorctl reload`
 
 ### To deploy changes
 - If supervisor/nginx conf files changed, copy them to those directories and restart services accordingly.
-- If Pipfile has changed, run `pipenv update`. (N.B. If the source of a package has changed, you may have to manually run `pipenv run pip uninstall ____` before updating so the old one is removed)
