Better documentation

[TwistingTwists]

Will you be willing to take up a better documentation on lines of https://github.com/dwyl/elixir-auth-google

I love how above mentioned repo answers all basic questions like what why who how when etc.

Your input needed on :

1. What is your pain point with present documentation ?
2. Is there an awesome feature that has not been described in detail?
3. If you can give a high level idea (maybe 3 steps) on how this library works.

Let me know. I am willing to contribute to better documentation.
