-## Wiki
+## Getting Started
-Configuration examples can be found at [/docs/config.yaml](https://github.com/MetaCubeX/Clash.Meta/blob/Alpha/docs/config.yaml), while documentation can be found [Clash.Meta Wiki](https://clash-meta.wiki).
+Documentations are now moved to [GitHub Wiki](https://github.com/Dreamacro/clash/wiki).
 
-## Build
+## Advanced usage for this branch
 
-You should install [golang](https://go.dev) first.
+### DNS configuration
-
-Then get the source code of Clash.Meta:
-
-```shell
-git clone https://github.com/MetaCubeX/Clash.Meta.git
-cd Clash.Meta && go mod download
-```
-
-If you can't visit github,you should set proxy first:
-
-```shell
-go env -w GOPROXY=https://goproxy.io,direct
-```
-
-Now you can build it:
-
-```shell
-go build
-```
-
-If you need gvisor for tun stack, build with:
-
-```shell
-go build -tags with_gvisor
