+### Use glob patterns
+
+Glob patterns (`*`, `?`, `[...]`, and `**`) are expanded by the action using
+[`@actions/glob`](https://github.com/actions/toolkit/tree/main/packages/glob),
+so they work consistently across Linux, macOS, and Windows runners. This action
+does not emulate Bash, PowerShell, or other shell-specific glob expansion.
+
+Hidden files and directories are skipped by default; target them explicitly, for
+example with `.venv/**/*.py`, to include them. If a pattern does not match any
+files, the original pattern is passed to Ruff so Ruff can report the missing
+path. Literal glob metacharacters in file or directory names must be escaped
+using `@actions/glob` syntax.
+
+```yaml
+- uses: astral-sh/ruff-action@v3

+    src: "src/**/*.py"
+```
+
+> [!NOTE]
+> When using multiple patterns, only the first is used to search for
+> `pyproject.toml` to determine the Ruff version. Use the `version` input
+> for explicit control. Large glob expansions may hit command-line length limits,
+> especially on Windows.

 ### Use to install ruff
 
 This action adds ruff to the PATH, so you can use it in subsequent steps.
