     `goctl` 读作 `go control`，不要读成 `go C-T-L`。`goctl` 的意思是不要被代码控制，而是要去控制它。其中的 `go` 不是指 `golang`。在设计 `goctl` 之初，我就希望通过 ` 她 ` 来解放我们的双手👈
 
     ```shell

    `goctl`can be read as `go control`. `goctl` means not to be controlled by code, instead, we control it. The inside `go` is not `golang`. At the very beginning, I was expecting it to help us improve the productivity, and make our lives easier.
 
    ```shell
+   # for Go 1.15 and earlier
    GO111MODULE=on go get -u github.com/tal-tech/go-zero/tools/goctl

+   # for Go 1.16 and later
+   go install github.com/tal-tech/go-zero/tools/goctl@latest
    ```
 
    make sure goctl is executable.
