 Custom rules allow you to create tailored rules to suit the exact needs of your applications and security policies. Now, you can restrict access to your web applications by country/region. As with all custom rules, this logic can be compounded with other rules to suit the needs of your application.
 
+To create a geo-filtering custom rule, simply select *Geo-location* as the Match Type, and then select the country or countries you want to allow/block from your application. See [how to create custom rules in Powershell](configure-waf-custom-rules.md) and more custom rule examples(create-custom-waf-rules.md) for more information.
