+Declaring dependency groups: the ``[dependency-groups]`` table
 ===================================================
 
 This specification defines Dependency Groups, a mechanism for storing package requirements in
 ``[pyproject.toml]`` files such that they are not included in project metadata when it is built.
 
 Dependency Groups are suitable for internal development use-cases like linting and testing, as well as for projects which are not built for distribution, like collections of related scripts.
 
-
 The `[dependency-groups]` table is an optional top-level table that allows defining non-distribution dependencies used for internal tooling, such as testing or linting.
 
 For the full specification and behavior, refer to the [Dependency Groups specification](https://packaging.python.org/en/latest/specifications/dependency-groups/).
