Just create a composer.json file with following content and run composer install

{ "require": { "php": ">=5.3", "nhagemann/anycontent-repository-mysql-php": "0.9.*" }, "scripts": { "post-update-cmd": "AnyContent\Repository\Command\Installer::postInstallUpdate", "post-install-cmd": "AnyContent\Repository\Command\Installer::postInstallUpdate"

},
"minimum-stability": "dev",
"prefer-stable": true

}

Then configure your webserver to server the content of the /web folder, e.g. as acrs.dev.

Go to the /config folder and copy the file modules.example.php to modules.php.

Have a look into that file, if you want to customize your installation. You can turn off any module by removing it's registration call ($app->registerModule()) within this file.

Go to the /config folder and copy the file config.example.yml to config.yml.

Within that file you have to specify at least your database connection.
