 ## Precedence
 
-In general, the dynamic configurations will take precedence over the configurations in YML. Specifically, when there is non empty CSP rules configured in the index, the rules from the YML will be used. To prevent `clickjacking`, we will append the `frame-ancestors` directive with value `'self'` if the rules from YML will be used and do not already have the directive `frame-ancestors`.
+Dynamic configurations override YAML configurations, except for empty CSP rules. To prevent `clickjacking`, a `frame-ancestors: self` directive is automatically added to YAML-defined rules that lack it.
