# Calibre-web # Calibre-web
## Overview ## Overview
This stack provides a fully automated setup for Calibre-web in NetGrimoire, utilizing Docker Swarm to manage the service. The main services used are calibre-web-automated and caddy. The Calibre-web stack is a Docker Swarm configuration for hosting the Calibre-web application in NetGrimoire. The service uses the crocodilestick/calibre-web-automated image, which includes automated setup and upgrade scripts.
