Installation problems

[basemaly]

Hi, there. I'm very excited to try your project. As you wrote in the instructions, I replaced the body of the get data function to this:

func GetData(sourcesMap map[string]schema.Record) map[string]schema.Data {
	return make(map[string]schema.Data)
	return data
}

And I created a new folder called 'data' inside apollo\pkg\apollo. However, when I try to launch, I get this error:

pkg\apollo\sources\source.go:14:9: undefined: data

Can you please help get it to work? Thanks!
