-      "quote": "Vue-cli 3.x is a complete rewrite, with a lot of new awesome features. You will be to select features like routing, Vuex or Typescript, then add and upgrade building blocks called \"vue-cli plugins\". But having so much more options also means the tool is now more complex and harder to start using. That's why we thought having a full-blown GUI would help discover the new features, search and install vue-cli plugins and unlock more possibilities overall while not being limited by a terminal interface. To sum up, vue-cli will not only allow you to bootstrap a new project easily, but it will also remain useful for ongoing work afterwards!",
