Documentation about payload wrong?

[agoodno]

From the README.md: "However, the payload does already contain the params hash, so you can easily add it in manually using custom_options:"

Should that read "However, the payload does NOT already contain..."? If so, I can fix it and create a PR for it.

I believe the documentation is correct, the params can be accessed/retrieved, but it is not included by default in the log output.
