Before you start with your new store, you should have set up a Shopware 6 instance. There are several ways how to set up your instance. Below you will find my fastest and favorite method.
Installation with All-Inkl
If you don’t have a server provider yet, you can choose the price-performance winner All-Inkl. I recommend this provider to all my customers and also use it myself. The big advantage is that Shopware 6 can be installed directly from the technical administration of the web server. This saves a lot of time and, for example, the manual creation of databases, etc.:

Shopware 6 kann ohne Server in der Cloud genutzt werden. You do not need your own server, just your own domain. Please note that the cloud version of Shopware 6 can only be used conditionally expandable through apps.
