Hi @nitishkumar71 .. I'm wondering how people can run these examples? And how can we maintain them over time?

Can you add a README file?

Perhaps we can take inspiration from github-go, and create a folder for each example with a main.go?

Sounds good to me.

I will do it.

I like the new structure, just a suggestion:

	fns, err := client.GetFunctions(context.Background(), "openfaas-fn")
	if err != nil {
		fmt.Fprintf(os.Stderr, "Get Failed: %s\n", err)
		os.Exit(1)
	}

vs

	fns, err := client.GetFunctions(context.Background(), "openfaas-fn")
	if err != nil {
		log.Printf("Get Failed: %s", err)
	}

This ran further code when I didn't have a valid gateway, instead of exiting.

and fmt vs log
