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