-## 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).
+## Dashboard
 
-## Build
+A web dashboard with first-class support for this project has been created; it can be checked out at [metacubexd](https://github.com/MetaCubeX/metacubexd).
 
-You should install [golang](https://go.dev) first.
+## Configration example
 
-Then get the source code of Clash.Meta:
+Configuration example is located at [/docs/config.yaml](https://github.com/MetaCubeX/Clash.Meta/blob/Alpha/docs/config.yaml).
+
+## Docs
+
+Documentation can be found in [Clash.Meta Docs](https://clash-meta.wiki).
+
+## For development
+
+Requirements:
+[Go 1.20 or newer](https://go.dev/dl/)
+
+Build Clash.Meta:
 
 ```shell
 git clone https://github.com/MetaCubeX/Clash.Meta.git
 cd Clash.Meta && go mod download
+go build
 ```
 
-If you can't visit github,you should set proxy first:
+Set go proxy if a connection to GitHub is not possible:
 
 ```shell
 go env -w GOPROXY=https://goproxy.io,direct

-Clash add field `Process` to `Metadata` and prepare to get process name for Restful API `GET /connections`.
-
-To display process name in GUI please use [Razord-meta](https://github.com/MetaCubeX/Razord-meta).
