Not enough examples/documentation on usage

[gwuah]

First off, thanks for this tool.

I was trying to parse a simple yaml file like the one below and I couldn't find a helpful example.

- Ghana
- Mali
- Togo

I had to experiment several times before l I was able to parse it.
It would be nice if you added more examples. (I'm willing to contribute)

If anyone's interested in how I solved my problem 👇🏾

config, err := yaml.ReadFile("/database/seeds/countries.yml")

if err != nil {
	panic(err)
}

lst, ok := config.Root.(yaml.List)
if !ok {
	panic("failed to parse")
}

for i := 0; i < lst.Len(); i++ {
	item := lst.Item(i)
	fmt.Println(item)
}
