+#### Code structure
+
+```javascript
+<template>
+  <!-- HTML Template -->
+</template>
+
+<script>
+  export default {}
+</script>
+
+<style>
+</style>
+```
+
+The template part contains the HTML of the component.
+
+The script tag contains the code defining the custom behavior of the component.
+
+The style tag houses the CSS of the component.
+
+src/components and src/views contain all our components.
+
+#### Folder Structure
+
+Let’s go through the folder structure of our newly created Vue project
+
+*public *— contains the main HTML file of our project
+
+*src/assets *— stores the media files like images, logos, etc.
+
+*src/components *— stores all the reusable components of our project. These components are not unique to some specific route.
+
+Apart from this, we have some important files too
+
+*App.vue *— it is the root component of our project
+
+main.js **— it is the starting point of our project. Here we import our root component **App.vue, our router file index.js and createApp method. After this, we mount our root component to the DOM using the following statement:
+
+new Vue({
+render: h => h(App),
+}).$mount('#app')
