 ## Firwall Policy Rules Format
 
-In a [firewall policy rule](https://cloud.google.com/firewall/docs/firewall-policies-rule-details), you specify a set of components that define what the rule does. Some of the values are optional and some have default value. See [Inputs](#Inputs). For sample code check [global](https://github.com/terraform-google-modules/terraform-google-lb-http/tree/master/examples/global-network-firewall-policy) and [regional](https://github.com/terraform-google-modules/terraform-google-lb-http/tree/master/examples/regional-network-firewall-policy) in [examples](https://github.com/terraform-google-modules/terraform-google-lb-http/tree/master/examples/) folder.
