+# Async plugin for LiveKit Agents
+
+Support for text to speech with [Async](https://async.ai/).
+
+See https://docs.livekit.io/agents/integrations/tts/asyncai/ for more information.
+
+## Installation
+
+```bash
+pip install livekit-plugins-asyncai
+```
+
+## Pre-requisites
+
+You'll need an API key from Async. It can be set as an environment variable: `ASYNCAI_API_KEY`
