Configuration
Merx works out of the box. What you configure is what makes it your shop: your currency, your tax rates, your payment keys.
Everything on the following pages is set in /site/config/config.php under the wagnerwagner.merx. prefix. The config options reference lists every option with its default value.
Start with currencies and taxes — they decide what a price means and are used by everything else. Stripe/PayPal secrets connects your payment provider, and testing and production is what you change last, when the shop goes live.
Never commit Stripe or PayPal secrets to a repository. Stripe/PayPal secrets shows where to keep them instead.
