 The CLI interface of OutlineVPN client for Linux.
 
-## Usage
-
-#### Standard
-
-```
-./outline-cli -transport "ss://<outline-server-access-key>"
-```
-
-#### Advanced (with Golang)
+### Usage
 
 ```
 go run github.com/Jigsaw-Code/outline-sdk/x/examples/outline-cli@latest -transport "ss://<outline-server-access-key>"
 ```
 
-### Arguments
-
 - `-transport` : the Outline server access key from the service provider, it should start with "ss://"
 
-## Build (for Developers)
+### Build
+
+You can use the following command to build the CLI.
 
-We recommend to setup a [go workspace](https://go.dev/blog/get-familiar-with-workspaces) to build the code. Then use the following command to build the CLI (only support Linux):
 
 ```
 cd outline-sdk/x/examples/
 go build -o outline-cli  -ldflags="-extldflags=-static" ./outline-cli
 ```
+
+> 💡 `cgo` will pull in the C runtime. By default, the C runtime is linked as a dynamic library. Sometimes this can cause problems when running the binary on different versions or distributions of Linux. To avoid this, we have added the `-ldflags="-extldflags=-static"` option. But if you only need to run the binary on the same machine, you can omit this option.
