 - Keep alive (restart if it exits)
 - Log stdout/stderr to `~/Library/Logs/mcquack.<scriptname>.{out,err}.log`
 
+## Development
+
+mcquack uses [uv](https://github.com/astral-sh/uv) for dependency management. Thanks to the
+uv shebang at the top of `mcquack.py`, you can always run the script directly without any
+setup:
+
+```bash
+./mcquack.py list
+```
+
+This works for users and developers alike—no virtual environment activation or `python`
+command needed. uv handles everything automatically.
+
+### Running Tests
+
+```bash
+uv run pytest
+```
+
+### Virtual Environment (Optional)
+
+If you prefer working in a virtual environment (e.g., for IDE support or running
+`python mcquack.py` directly), you can create and activate one:
+
+```bash
+uv venv
+source .venv/bin/activate
+```
+
+After activation, `python mcquack.py` will work as expected. But again, `./mcquack.py`
+always works without this step.
