1. Set Environment to "production" and Timezone to "America/New_york" in manual install
2. leave blank "Database Admin user name" and "database Admin pass" in manual install
3. PHP REQUIREMENT LINK : http://whatacart.com/installation and also check vendor/composer/platform_check.php
4. Copy "resources" folder from manual install to our package exclude "resources/images/thumbs" folder
5. Install with Demo Data 
6. Download a package using composer as no vendor folder in there in their zip package. (Since 2.0.7)
composer create-project ushainformatique/whatacart
7. Keep "tbl_customer" entries as it is because these are random users.
8. We have disabled this script on AMPPS because getting "internal server error" on accessing any module. i.e no products, category, settings getting created on ampps. (even in manual) 
9. Script is not working on PHP 8.0+ hence we have restricted it. Vendor haven't specified in the docs. Check in next versions.
10. Before installing, keep error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT in php.ini, to avoid internal server error. Recommended by vendor
