+## Setting a shebang
+
+You can use the following shebang (`#!`) line at the top of your script to have your system pick
+`uv` for running it:
+
+```python title="example.py"
+#!/usr/bin/env -S uv run --script
+# /// script
+# dependencies = []
+# ///
+```
+
+You can then make the script executable and launch it without explicitly calling `uv`:
+
+```bash
+chmod +x example.py
+./example.py
+```
+
