 # Apache Arrow Flight
 
+[![Crates.io](https://img.shields.io/crates/v/arrow-flight.svg)](https://crates.io/crates/arrow-flight)
+
 Apache Arrow Flight is a gRPC based protocol for exchanging Arrow data between processes. See the blog post [Introducing Apache Arrow Flight: A Framework for Fast Data Transport](https://arrow.apache.org/blog/2019/10/13/introducing-arrow-flight/) for more information.
 
 This crate simply provides the Rust implementation of the [Flight.proto](../../format/Flight.proto) gRPC protocol and provides an example that demonstrates how to build a Flight server implemented with Tonic.
 
 Note that building a Flight server also requires an implementation of Arrow IPC which is based on the Flatbuffers serialization framework. The Rust implementation of Arrow IPC is not yet complete although the generated Flatbuffers code is available as part of the core Arrow crate.

 Run `cargo build` or `cargo build --release` to build in release mode.
 Some features take advantage of SSE4.2 instructions, which can be
 enabled by adding `RUSTFLAGS="-C target-feature=+sse4.2"` before the
 `cargo build` command.
 
 ## Test

 Run `cargo test` for unit tests. To also run tests related to the binaries, use `cargo test --features cli`.
 
 ## Binaries
