Title: Documentation for meta and meta_key options

I needed to use these features, there was no mention of it's existence on documentation, so I looked into the de code base to find out about its existence. Thought someone else would have the same need.

I don't know if the place I chose to place it is ok or not, if any changes are needed please let me know.

Thanks this is a great gem.
