+## Quick Start
+
+A simple Go example code that compiles/runs Tengo script code with some input/output values:
+
+```golang
+package main
+
+import (
+ "context"
+ "fmt"
+
+ "github.com/d5/tengo/v2"
+)
+
+func main() {
+ // Tengo script code
+ src := `
+each := func(seq, fn) {
+ for x in seq { fn(x) }
+}
+
+sum := 0
+mul := 1
+each([a, b, c, d], func(x) {
+ sum += x
+ mul *= x
+})`
+
+ // create a new Script instance
+ script := tengo.NewScript([]byte(src))
+
+ // set values
+ _ = script.Add("a", 1)
+ _ = script.Add("b", 9)
+ _ = script.Add("c", 8)
+ _ = script.Add("d", 4)
+
+ // run the script
+ compiled, err := script.RunContext(context.Background())
+ if err != nil {
+ panic(err)
+ }
+
+ // retrieve values
+ sum := compiled.Get("sum")
+ mul := compiled.Get("mul")
+ fmt.Println(sum, mul) // "22 288"
+}
+```
