      examples <<~DOC
        Sleep for 10 seconds
        ```ruby
        chef_sleep '10'
        ```

        Sleep for 10 seconds with a descriptive resource name for logging
        ```ruby
        chef_sleep 'wait for the service to start' do
          seconds 10
        end
        ````

        Use a notification from another resource to sleep only when necessary
        ```ruby
        service 'Service that is slow to start and reports as started' do
          service_name 'my_database'
          action :start
          notifies :sleep, chef_sleep['wait for service start']
        end

        chef_sleep 'wait for service start' do
          seconds 30
          action :nothing
        end
        ```
