## Handlers

Handlers are tasks that only run when notified by other tasks (typically after a change):

```yaml
- name: Install nginx
  hosts: webservers
  tasks:
    - name: Install nginx
      apt:
        name: nginx
        state: present
      notify: Restart nginx

  handlers:
    - name: Restart nginx
      service:
        name: nginx
        state: restarted
```
