Initial settings after installation on the web server.

Could you give me an advice please? After uploading the Opencart package to the web server, after entering the domain in the browser, when I want to make the initial settings, the above text is displayed, I am also sending a printscreen in the attachment.
I do not know what to do with that.

Text:
