How to enable preview html per atom?

Question

atom

Good evening. I am a beginner, not even a programmer, but a user) the problem is this, I installed ATOM on both Windows 10 and Ubuntu. the problem is the same everywhere. I downloaded the previer html library, deleted it, reinstalled ATOM, rebooted everything, just didn’t do it) I want to immediately see the site that I get while printing the code, press ctrl + shift + H or try to press in the top menu to open the file view, and nothing opens. Well, I don’t want that at the very first step in studying the creation of sites, I stopped studying) tell me how can I open the view ???? thanks in advance.
