With Docca you can simply archive scanned documents.
You need to have ìnstalled (preferably on a linux system):
git
composer
php 7.1 (command line interface and webserver)
mysql database
php-imagick
Then you can set up the app with
$ git clone https://github.com/hajika/docca
$ cd docca
$ composer install
$ bin/console doctrine:schema:update -f
Then for development (only):
$ bin/console server:start
After that you should be able to run it in your browser with http://localhost:8000
Docca is alpha version in development and should not be used in productive environment yet
