-### Alpine
-
-Here is a script to install the solution on Linux Alpine (tested with version 3.15).
-Remember to edit the "domain" variable at the beginning of the script to match the URL it will be called with.
-
-The main components are:
-
-- php 8 + php-fpm
-- Nginx
-- pdftk ("manual" installation requiring openjdk8)
-- imagick
-- potrace
-- librsvg
-- ghostscript
-
-What the script does:
-
-- Installs dependencies
-- Configures php and php-fpm
-- Configures Nginx
-- Configures the config.ini
-- Clones the repo
-
-```
-#!/bin/sh
-
-domain='sign.example.com'

-apk update
