+# pty
+
+Pty is a Go package for using unix pseudo-terminals.
+
+## Install
+
+```sh
+go get github.com/creack/pty
+```
+
+## Examples
+
+Note that those examples are for demonstration purpose only, to showcase how to use the library. They are not meant to be used in any kind of production environment.
+
+### Command
+
+```go
+package main
+
+import (
+	"io"
+	"os"
+	"os/exec"
+
+	"github.com/creack/pty"
+)

+	f, err := pty.Start(c)
+	if err != nil {
+		panic(err)
+	}
+
+	go func() {
+		f.Write([]byte("foo\n"))
