+You can lookup arguments by calling the `Args` function on `cli.Context`, e.g.:
+
+<!-- {
+  "output": "Hello \""
+} -->
+```go
+package main
+
+import (
+	"fmt"
+	"log"
+	"os"
+
+	"github.com/urfave/cli/v2"
+)
+
+func main() {
+	app := &cli.App{
+		Action: func(cCtx *cli.Context) error {
+			fmt.Printf("Hello %q", cCtx.Args().Get(0))
+			return nil
+		},
+	}
+
+	if err := app.Run(os.Args); err != nil {
+		log.Fatal(err)
+	}
+}
+```
