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

+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:

+go build

+go build -tags with_gvisor
