 There are some basic examples in the `example` folder. But if you want to see the driver in action 
 take a look at [Vega](https://github.com/zookzook/vega), especially the [Board.ex](https://github.com/zookzook/vega/blob/master/lib/vega/board.ex) module for using the transaction api together with
 bulk operations.

 Special thanks to [JetBrains](https://www.jetbrains.com/?from=elixir-mongodb-driver) for providing a free JetBrains Open Source license for their complete toolbox.
 
 The [Documentation](https://hexdocs.pm/mongodb_driver/readme.html) is online, but currently not up to date. 
 This will be done as soon as possible. In the meantime, look in the source code. Especially 
 for the individual options.
