I'm new in GoLang.
I clone this project, how can I run a simple modbus/TCP holding register with these code files?

Hi ，you don't clone this.
With Golang,you just use "go get " to download this package and install it.
then,in your project,you have to set the "GoPath".
and next, you just "import " this package,you can use this package's method.
about "go get" of goland,I think you can google it.you will get lots of information about it.

Thanks, I set $GOPATH=$HOME/go in .bashrc and do go get github.com/goburrow/modbus.git in gopath location (~/go/) then I do go install github.com/goburrow/modbus/.
Then I create a go project and use go modbus library in my code.

This is my "gopath" tree:

go/
│── src
│   │── own_modbus
│   │   └── modbus.go
│   │
│   │── github.com
    │   └── goburrow
    │       ├── modbus
    │          ├──  . . .
              . . .

And this is my "own_modbus" code:

package main

import ("fmt"
	    "github.com/goburrow/modbus"
)

func main() {
	cli := modbus.TCPClient("192.168.1.150:502")
	res, err := cli.ReadHoldingRegisters(4096, 1)
	fmt.Println(res)
	fmt.Println(err)

}

Is there any "go modbus" documentation and examples such as pymodbus?
