OK, with little programming skills I can understand why it would be difficult to get HTML5 going. A step by step guide isn’t that easy to give and this is why HTML5 is still experimental. You’ll hit problems but ask and people will help. A lot of guides will assume some programming knowledge.
To start with you need to get the editor built and running. There are pretty solid steps on GitHub (https://github.com/EpicGames/UnrealEngine) or in the GitHub README.md (they are the same steps). Assuming that you’re running windows you need to get to the point where you can run the editor from Visual Studio.
Also be sure to run through the Getting started for HTML5 (Sharing and Releasing Projects for Unreal Engine | Unreal Engine 5.1 Documentation)
Once you’re able to run the editor, you need to build HTML5 for Blueprint only projects. For this you can use the Unreal Frontend. From visual studio you set your project to “Unreal Frontend”, config to “Development” and “Win64”. Then find the UnrealFrontend project in the Solution Explorer, right click and select “Build”.
Once it finishes you can use the steps Moss gave (Html5 build issue - Platform & Builds - Epic Developer Community Forums) to get your project running.
