 9 | ### Online demo
10 | 
11 | https://wemboava.github.io/vue-scrollup-menu
12 | 
13 | ## Getting Started
14 | 
15 | ### install
16 | ``` npm i vue-scrollup-menu ```
17 | 
18 | ### Use
19 | 
20 | ```vue
21 | <template>
22 |     <header v-vue-scrollup-menu class="header"></header>    
23 | </template>
24 | ```
25 | 
26 | ### Import directive
27 | 
28 | ```vue
29 | <script>
30 |     import vueScrollupMenu from 'vue-scrollup-menu'
31 | 
32 |     export default {
33 |         name: 'Header',
34 | 
35 |         directives: {
36 |             vueScrollupMenu
37 |         },
38 |     }
39 | </script>
40 | ```
41 | 
42 | ##### Or use directive globally
43 | 
44 | ```javascript
45 | import Vue from 'vue'
46 | import vueScrollupMenu from 'vue-scrollup-menu'
47 | 
48 | Vue.directive('vue-scrollup-menu', vueScrollupMenu)
49 | ```
