 # swiftnav-rs
 
-An idiomatic Rust wrapper around the C library [`libswiftnav`](https://github.com/swift-nav/libswiftnav), which provides
-general GNSS related functionality.
+`swiftnav-rs` is a crate that implements GNSS utility functions for use by software-defined GNSS receivers or software requiring GNSS functionality. It is intended to be as portable as possible and has limited dependancies
+
+`swiftnav-rs` does not provide any functionality for communicating with Swift
+Navigation receivers.  See [libsbp](https://github.com/swift-nav/libsbp) to
+communicate with receivers using Swift Binary Protocol (SBP).
