+This project demonstrates **how to enable interactive sky visualization** in Python data apps by
+combining [ipyaladin](https://github.com/cds-astro/ipyaladin) and [Panel](https://panel.holoviz.org/index.html).
+
+The [examples](examples) are resembling the examples at [ipyaladin/examples](https://github.com/cds-astro/ipyaladin/tree/master/examples).
+
+Created by [awesome-panel](https://awesome-panel.org).
+
+## Install
+
+```bash
+pip install -r requirements_dev.txt
+```

+## Serve
+
+```bash
+panel serve examples/*.py --dev --static-dirs thumbnails=./thumbnails
+```
+
+## Ruff
+
+```bash
+ruff format
