+# Haskell example
+
+To run the example, make sure you put an ``example.wav`` in this directory, and then run the following:
+```bash
+stack run
+```
+
+The ``example.wav`` file must have the following requirements:
+- Must be 16khz sample rate.
+- Must be mono channel.
+- Must be 16-bit audio.
+
+This uses the [silero-vad](https://hackage.haskell.org/package/silero-vad) package, a haskell implementation based on the C# example.
