 - Netfilter TCP redirecting. Deploy Clash on your Internet gateway with `iptables`.
 - Comprehensive HTTP RESTful API controller

-## Wiki
+## Getting Started
+Documentations are now moved to [GitHub Wiki](https://github.com/Dreamacro/clash/wiki).

-Documentation and configuring examples are available on [wiki](https://github.com/MetaCubeX/Clash.Meta/wiki) and [Clash.Meta Wiki](https://docs.metacubex.one/).
+## Advanced usage for this branch

-## Build
-
-You should install [golang](https://go.dev) first.
-
-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
-```
