 Rust Wave File Reader/Writer with Broadcast-WAV, MBWF and RF64 Support
 
 This is currently a work-in-progress!
+
+## Use
+
+```rust
+
+let path = "tests/media/ff_silence.wav";
+
+let mut w = WaveReader::open(path)?;
+let length = w.frame_length()?;
+let format = w.format()?;
+
+let bext = w.broadcast_extension()?;
+println!("Description field: {}", &bext.description);
+println!("Originator field: {}", &bext.originator);
+
+let frame_reader = w.audio_frame_reader()?;
+
+let mut buffer: Vec<i32> = w.create_frame_buffer();
+while( frame_reader.read_integer_frame(&mut buffer) > 0) {
+    println!("Read frames {:?}", &buffer);
+}
+
+```
+
+## Note on Testing
+
+All of the media for the integration tests is committed to the respository
+in either zipped form or is created by ffmpeg. Before you can run tests,
+you need to `cd` into the `tests` directory and run the `create_test_media.sh`
+script.
