Update usage information

[jeremylynch]

Is it possible to improve the readme to show more use cases for this gem?

For example, it would be good to know how to retrieve a particular version etc

Hello @mrjlynch. It will be good to have better documentation.

Since the code has very good test coverage. you can start here https://github.com/simi/mongoid-versioning/blob/master/lib/mongoid/versioning.rb and here https://github.com/simi/mongoid-versioning/blob/master/lib/mongoid/versioning.rb for now. I'll try to improve docs ASAP. If you'll have some spare time, feel free to send me PR. I will be verry happy!
