-Configuration example is located at [/docs/config.yaml](https://github.com/MetaCubeX/Clash.Meta/blob/Alpha/docs/config.yaml).
+Support `geosite` with `fallback-filter`.
 
-## Docs
+Restore `Redir remote resolution`.
 
-Documentation can be found in [Clash.Meta Docs](https://clash-meta.wiki).
+Support resolve ip with a `Proxy Tunnel`.
