 ### <a name="redirect-syntax"></a> Syntax
 
-AdGuard uses the same filtering rule syntax
-as [uBlock Origin](https://github.com/gorhill/uBlock/wiki/Static-filter-syntax#redirect).
+AdGuard uses the same filtering rule syntax as [uBlock Origin][ubo-redirect].
 Also, it is compatible with ABP `$rewrite=abp-resource` modifier.
 
-`$redirect` is a modifier for
-[the basic filtering rules](https://kb.adguard.com/en/general/how-to-create-your-own-ad-filters#basic-rules-syntax)
+`$redirect` is a modifier for [the basic filtering rules][kb-basic-rules]
 so rules with this modifier support all other basic modifiers like `$domain`, `$third-party`, `$script`, etc.
 
 The value of the `$redirect` modifier must be the name of the resource that will be used for redirection.
 See the list of [available redirect resources](./wiki/about-redirects.md#redirect-resources).
 
+> Priority of `$redirect` rules is described in the [Knowledge Base][kb-redirect-priority].
+
 ### Examples
 
 - `||example.org/script.js$script,redirect=noopjs` — redirects all requests to `script.js`
   to the resource named `noopjs`.
 - `||example.org/test.mp4$media,redirect=noopmp4-1s` — requests to `example.org/test.mp4` will be redirected
   to the resource named `noopmp4-1s`.
 
-> `$redirect` rules priority is higher than the regular basic blocking rules' priority.
-> This means that if there's a basic blocking rule (even with `$important` modifier),
-> `$redirect` rule will prevail over it.
-> If there's a whitelist (`@@`) rule matching the same URL,
-> it will disable redirecting as well (unless the `$redirect` rule is also marked as `$important`).
-
 > uBlock Origin specifies additional resource name `none` that can disable other redirect rules.
 > AdGuard does not support it, use `$badfilter` to disable specific rules.
