 # Mongo Rust Driver
 
+[![Build Status](https://travis-ci.org/thijsc/mongo-rust-driver.svg)](https://travis-ci.org/thijsc/mongo-rust-driver)
+
 ## About
 
 Mongo Rust driver built on top of the [Mongo C driver](https://github.com/mongodb/mongo-c-driver).
-This drivers aims to be a thin wrapper around the production-ready C driver, while providing a safe
-and ergonomic Rust interface that handles all the gnarly usage details of the C driver for you.

-Bson encoding and decoding is handled by the [bson crate](https://github.com/zonyitoo/bson-rs), the bindings
-are based on generated bindings by [bindgen](https://github.com/crabtw/rust-bindgen).

 The API should still be considered experimental, but I'm not expecting changes at the moment.
