configuration template includes "postcss-preset-env" plugin, however it does not tell you to install it

Modification Proposal

Expected Behavior / Situation

In Getting Started section, it should tell you to also install postcss-preset-env because in the provided boilerplate-configuration, the plugin is used.
This line npm install --save-dev postcss-loader postcss should change to npm install --save-dev postcss-loader postcss postcss-preset-env.

Actual Behavior / Situation

The Getting Started guide does not tell you to install postcss-preset-env.
