 This repository holds the Dockerfile and associated files needed to build [dasskelett:nginx-quic](https://hub.docker.com/r/dasskelett/nginx-quic),
 a nginx image compiled from the [nginx-quic branch](https://hg.nginx.org/nginx-quic) with support for HTTP/3 and QUIC.
 The image is based on `archlinux:base-devel` to make use of the [nginx-quic](https://aur.archlinux.org/packages/nginx-quic/) AUR package.
+The Dockerfile is loosely oriented on the [Dockerfile](https://github.com/nginxinc/docker-nginx/blob/master/mainline/alpine/Dockerfile) for the official [nginx:alpine](https://hub.docker.com/_/nginx) image.
 
 Containers will listen for HTTPS (HTTP/1.1 via TLS, HTTP/2 via TLS, HTTP/3 via QUIC) connections on port 443 by default.
 The image contains a self-signed certificate for this reason.
 
 Keep in mind that HTTP/3+QUIC support in nginx is still WIP.
