+### Dynamic Modals
+
+In order to instantiate modals at runtime (for lazy-loading or decluttering templates), it is possible to create modals dynamically.
+
+To start using this feature you must set `dynamic: true` in plugin configuration:
+
+```js
+Vue.use(VModal, { dynamic: true })
+```
+
+And include the `<modals-container/>` component it in your project:
+
+```vue
+<modals-container/>
+```
+
+Call it (the first argument is the component definition, the second are component properties, and the third modal parameters):
+
+```javascript
+this.$modal.show({
+  template: `
+    <div>
+      <h1>This is created inline</h1>
+      <p>{{ text }}</p>
+    </div>
+  `,
+  props: ['text']
+}, {
+  text: 'This text is passed as a property'
+})
+```
+
+It can also be used with `.vue` files:
+
+```javascript
+import MyComponent from './MyComponent.vue'
+
+this.$modal.show(MyComponent, {
+  text: 'This text is passed as a property'
+}, {
+  draggable: true
+})
+```
+
 For more examples please take a look at [vue-js-modal.yev.io](http://vue-js-modal.yev.io).
