install.md

Automated Server Setup with Caddy and Docker

This script automates the setup of a web server using Caddy, Docker, PM2 and Node.js. It includes PHP-FPM support and automated SSL certificate management.

Prerequisites

  1. Debian server (will work on other distros but debian is what this was made for)
  2. For Vultr: Enable Limited User Login feature

Installation Script
