+Being a programmer can be a lonely job. Thankfully by the power of automation that is not the case! Let's create a greeter app to fend off our demons of loneliness!
+
+``` go
+/* greet.go */
+package main
+
+import "os"
+import "github.com/codegangsta/cli"
+
+func main() {
+  cli.Name = "greet"
+  cli.Usage = "fight the loneliness!"
+  cli.Action = func(c cli.Context) {
+    println("Hello friend!")
+  }
+  
+  cli.Run(os.Args)
+}
+```
+
+Install our command to the `$GOPATH/bin` directory:
+
+```
+$ go install
+```
+
+Finally run our new command:
+
+```
+$ greet
+Hello friend!
 ```
