Write formal documentation

[leonelquinteros]

Please describe your issue

The only documentation for this package is Godoc and the README.md file from this repo. We need to write better docs, some tutorial and use case examples to make package adoption easier.

Is this a bug, an improvement, a proposal or something else? Describe it.

Improvement

What's the expected behaviour, the current behaviour and the steps to reproduce it?

We don't have documentation. We want to have documentation
