@subdavis Would you have any guidance to address these warnings reported when running yarn install?

If you want them to go away, you can yarn add --peer webpack@^4.0.0, but it will only make the problem more confusing. Vue CLI wraps webpack, and its wrapped version is the one that will always be used. If you end up with a version conflict where, for example, sass-loader depends on a version of webpack different than the one embedded in the vue cli dependency, yarn won't be able to tell you about it.

The true expression of dependencies would be "sass-loader has either webpack@version or vue-cli@version as a peer dependency", but it can't, so this is what you get.

I recommend keeping these warnings.

Well if so, can you put some note into the documentation please as it's a bit worrying to see stuff like this when you're learning!!!
