# Foundry + Nginx install script for Debian 12
# --------------------------------------------

# Perequisites:
# - unzip   - used to decompress Foundry once downloaded
# - nodejs  - required to run Foundry
# - nvm     - used to install pm2
# - ufw     - firewall: used to ensure that connections can only be made to Foundry via Nginx, among other benefits
# - nginx   - provides HTTPS frontend to Foundry
# - certbot - gets free SSL certificate, used by Nginx
