If you want to work locally before putting your site online follow these steps

1 Download repo

2 Installation

Import the installation.sql into your database.

Open a command prompt and type the command composer install
Wait and when it's finished, go to your project url and work with this!

composer dump-env prod and composer install --no-dev --optimize-autoloader

I would not provide any support in case of changing the project sources for basic systems.

If you create a new system no support will also be done.

I provide support only for installation, theme modification and how to use basic systems.
