3bcba4053e Update README.md (#95)
I tried copying the sample code as it is but did not do what I assumed.
Specifically, it is as follows.

- It does not work without `require_once`
- I can not check the output if it is `return`

I modified the README.md.
I think that this one is better.
Because you can use it as soon as you copy it.
