DotConfig is a free tool (and always will be) to make configurations for web projects easier. It currently supports Webpack but soon will have wizards other web technologies.
Besides being a configuration wizard, DotConfig will also have content on configuring web technologies, what the options are and why you would want to add them to your project.
I've worked with Webpack a few times for a few different projects. When I was a beginner, it was hard for me to wrap my head around Webpack. I got the hang of it eventually but Webpack has a lot of options which is hard to keep track of and use in my projects.
