+## Usage
+
+### Speech-to-Text support
+
+If you have [whisper.el](https://github.com/natrys/whisper.el/blob/master/whisper.el) installed you can use the `eca-chat-talk`
+command (or use the `C-t` keybinding) to talk to the Editor Code
+Assistant. This will record audio until you press `RET`. Then, the
+recorded audio will be transcribed to text and placed into the chat
+buffer.
+
+We recommend to use the `small`, it is a good trade-off between
+accuracy and transcription speed.
+
+```elisp
+(use-package whisper
+  :custom
+  (whisper-model "small"))
