+# Dad Joke Greeter
+
+Greet participants with a random dad joke when they join your Tuple room — spoken aloud so everyone on the call hears it.
+
+Jokes are fetched from [icanhazdadjoke.com](https://icanhazdadjoke.com/) and played through macOS text-to-speech. Audio is routed to both your local speakers and a virtual audio device so remote participants hear the joke through Tuple.
+
+## Installation
+
+Copy the trigger into your Tuple triggers directory:
+
+```bash
+cp -r triggers/dad-joke-greeter ~/.tuple/triggers/dad-joke-greeter
+```
+
+> If you installed this trigger from the [Tuple Triggers Directory](https://tuple.app/triggers), it's already in place — skip to Quick Setup.
+
+## How it works
+
+- When **you** join a room, the trigger records which room you're in (no joke yet — you're alone).
+- When **someone else** joins the same room, a dad joke is fetched and spoken aloud.
+- When **you** leave the room, state is cleared and jokes stop.
+
+## Quick setup
+
+Run the included setup script to check prerequisites, create the audio device, and validate everything:
+
+```bash
+bash ~/.tuple/triggers/dad-joke-greeter/setup.sh
+```
+
+The script will walk you through each step interactively. If you prefer to set things up manually, follow the steps below.
+
+## Prerequisites
+
+- macOS (uses `say` for text-to-speech)
+- [jq](https://jqlang.github.io/jq/) (`brew install jq`)
+- [BlackHole 2ch](https://existential.audio/blackhole/) (free virtual audio driver)
+> **Note:** After installing BlackHole, you may need to restart your Mac (or log out and back in) before it appears as an audio device.
+
+## Manual audio setup
+
+The key trick is routing the `say` audio into Tuple's microphone input so remote participants hear the joke. This requires a virtual audio loopback device.
+
+### 1. Install BlackHole
+
+```bash
+brew install blackhole-2ch
+```
+
+### 2. Create an aggregate audio device
+
+Open **Audio MIDI Setup** (Spotlight → "Audio MIDI Setup") and create a new aggregate device:
+
+1. Click the **+** button in the bottom-left → **Create Aggregate Device**
+2. Name it **"BH + Mic Input"**
+3. Check **your preferred microphone first** — this can be any hardware mic (e.g. "MacBook Pro Microphone", an external USB mic, etc.)
+4. Check **"BlackHole 2ch" second**
+5. Enable **Drift Correction** on the BlackHole 2ch row
+6. Set the **Clock Source** to the microphone you selected in step 3
+
+> **Order matters.** Your hardware mic must be added first and used as the clock source. BlackHole needs drift correction enabled because it runs on a virtual clock that can drift from the hardware mic. Getting this wrong can cause audio glitches or silence.
+
+### 3. Configure Tuple
+
+In Tuple, go to **Preferences → Audio → Input Device** and select **"BH + Mic Input"**.
+
+Now Tuple receives both your voice (real mic) and the joke audio (BlackHole).
+
+### 4. Speaker device name
+
+During setup, the script automatically detects your audio output devices and writes the selected device into the `room-joined` script. No manual editing needed.
+
+If you skipped setup or need to change it later, update `SPEAKER_DEVICE` in the `room-joined` script. Find your device name with:
+
+```bash
+system_profiler SPAudioDataType | grep -A2 "Output Channels" | grep -v "Output Channels"
+```
+
+## Configuration
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `SPEAKER_DEVICE` | `MacBook Pro Speakers` | Local speaker device name |
+| `BLACKHOLE_DEVICE` | `BlackHole 2ch` | Virtual audio device name |
+
+## Limiting to specific rooms
+
+By default, jokes trigger in any room you join. To restrict to specific rooms, create `~/.tuple/tracked-rooms` with one room name per line:
+
+```
+Engineering
+Design Crit
+```
+> **Room names are case-sensitive and must match exactly.** Use the room name as it appears in Tuple.
+
+When this file exists, only rooms listed in it will trigger jokes. Remove the file to go back to all rooms.
+
+## Disabling temporarily
+
+Create a disable file to pause jokes without removing the trigger:
+
+```bash
+# Disable
+touch ~/.tuple/.dad-jokes-disabled
+
+# Re-enable
+rm ~/.tuple/.dad-jokes-disabled
+```
+
+> Tuple spawns trigger scripts as subprocesses, so environment variables set in your terminal don't propagate. The touch-file approach works reliably regardless of how the script is launched.
+
+Alternatively, remove or rename the trigger files in `~/.tuple/triggers/dad-joke-greeter/`.
+
+## Known limitations
+
+- **Switching microphones:** The aggregate audio device is configured with a specific mic. If you swap between multiple inputs throughout the day (e.g. AirPods, built-in mic, headset), you'll need to update the aggregate device in Audio MIDI Setup to use the new mic. A future version may automate this by detecting the current input and rebuilding the aggregate on the fly.
