+            Exclusions are based on globs, and can be either:
+
+            - Single-path patterns, like `.mypy_cache` (to exclude any directory named `.mypy_cache` in the
+              tree), `foo.py` (to exclude any file named `foo.py`), or `foo_*.py` (to exclude any file matching
+              `foo_*.py` ).
+            - Relative patterns, like `directory/foo.py` (to exclude that specific file) or `directory/*.py`
+              (to exclude any Python files in `directory`). Note that these paths are relative to the
+              project root (e.g., the directory containing your `pyproject.toml`).
+
+            Note that you'll typically want to use [`extend_exclude`](#extend_exclude) to modify
+            the excluded paths.
