I also suggest that in the download page there should be a field with core compatibilty. this is important for manual installations. Maybe also php version, platform and db compatibility.

Software COMPATIBILITY :

• Platform: UNA 11.X.X, UNA 12.1.0, UNA 13.1.X, ETC
• PHP: php.7.1, php7.4-fpm, php8.1-fpm, 8.2 (TESTET, ERROR, UNTESTED)
• DB: mysql-5.5.5, MariaDB 10.1, etc
• Webserver: Nginx 1.2, Apache, Tengine 1.15, etc
• Doc
• All issues
• Source code
• Auto instaler:

composer require 'una/messenger:^12.5'
docker run -it --rm --name my-running-app my-php-app

Download method

cd /una_project/
wget https://exemple.com
or
gh repo clone unaio/jot-client-una
or
etc

Don't forget that this shop is not just just about UNA, those who sell software on the Internet will find these things very useful in their market store. For them as sellers and for the customer who buys these details are important. Composer installer or other methods, like dokker, etc also its useful. All this data could be automatically extracted from the file info.txt or another extension, by the app market itsfel, just by providing the location of the file, so it can display this information in a simple and efficient way.
