Are docs outdated for the config object?

[everdimension]

Hi! Thanks for an awesome library

I find that some APIs are poorly documented and have trouble figuring out some methods.

Here's the place in the docs that implies that the config object that is passed to the task has a values() method:
https://github.com/sapegin/mrm/blob/1f729751b46ad583c9e09c74f75fcf23772b665f/docs/FAQ.md#how-to-infer-github-user-name

But I stumbled upon a library that crashed trying to call this method

I can't find proper documentation for the config object in the docs. Can you help me find it in the code?
