 the version is `1.0.1` will be rejected by uv, but accepted by pip.
 
 To force uv to accept such wheels, set `UV_SKIP_WHEEL_FILENAME_CHECK=1` in the environment.

+## Package name normalization
+
+By default, uv normalizes package names to match their
+[PEP 503-compliant forms](https://packaging.python.org/en/latest/specifications/name-normalization/#name-normalization)
+and uses those normalized names in all output contexts. This differs from pip, which tends to
+preserve the verbatim package name as published on the registry.
+
+For example, `uv pip list` displays normalized packages names (e.g., `docstring-parser`), while
+`pip list` displays non-normalized package names (e.g., `docstring_parser`):
