The getting-started tutorial doesn’t work on windows

I’m new to webpack 1.9.11 and are following the getting-started tutorial. Unfortunately I can only get to Binding loaders, where I get the following error:

C:\Users\dotnet\Projects\playground\webpack_tut (master)

You may need an appropriate loader to handle this file type.

My entry.js:

require("./style.css");
document.write(require("./content.js"));

My style.css:

body {
    background: yellow;
}
