+# Hush
+
+A Linux speech-to-text daemon that records audio, transcribes it via the Groq Whisper API, optionally cleans up the text with an LLM, and types the result into whatever window currently has focus.
+
+The intended workflow: bind `hush toggle` to a global hotkey, press to start recording, press again to stop, and the transcribed text appears in your active application.
+
+## Requirements
+
+**Runtime dependencies:**
+
+- [pw-record](https://pipewire.org/) (PipeWire) or `ffmpeg` (PulseAudio) — audio capture
+- [wtype](https://github.com/atx/wtype) (Wayland) or [xdotool](https://github.com/jordansissel/xdotool) (X11) — text injection
+- `notify-send` — desktop notifications
+- A [Groq API key](https://console.groq.com/)
+
+**Build dependencies:**
+
+- [.NET 10.0 SDK](https://dotnet.microsoft.com/download/dotnet/10.0)
+
+## Installation
+
+```bash
+sudo ./install.sh
+```
+
+This builds the project, installs the `hush` binary to `/usr/bin/hush`, sets up zsh tab-completion, and registers `hush.service` as a systemd (or OpenRC) user service.
+
+To uninstall:
+
+```bash
+sudo ./uninstall.sh
+```
+
+## Setup
+
+After installing, run the interactive setup wizard to configure your API key and preferences:
+
+```bash
+hush setup
+```
+
+Config is stored at `~/.config/hush/config` in TOML format.
+
