+    When using `uv build`, uv acts as a [build frontend](https://peps.python.org/pep-0517/#terminology-and-goals)
+    and only determines the Python version to use and invokes the build backend. The details of
+    the builds, such as the included files and the distribution filenames, are determined by the build
+    backend, as defined in [`[build-system]`](./config.md#build-systems). Information about build
+    configuration can be found in the respective tool's documentation.
