+---
+
+Nuxt automatically imports any directive in this directory (along with directives that are registered by any modules you may be using).
+
+```bash [Directory Structure]
+| directives/
+--| awesome.ts
+--| focus.ts
+```
+
+```html [app.vue]
+<template>
+  <div v-awesome v-focus>
+  </div>
+</template>
+```
+
+## Directives
+
+You must use always named exports for your directives.
+
+If you have SSR enabled, you must use object notation in your directives. Otherwise, Vue will throw an error about missing `getSSRProps`.
+
+```ts
+function mounted (el: HTMLElement, binding: TouchDirectiveBinding) {
+  // ...
+}
+
+// other lifecycle hooks
+
+export const Focus = {
+  mounted
+  // ...
+}
+
+// DONT' USE export default here
+export default Focus
+```
