+``bazel`` for Bazel modules as specified at ``https://bazel.build/external/module``:
+
+- The default repository is the Bazel Central Registry (BCR) ``https://bcr.bazel.build``.
+- The ``name`` is the module name.
+- The ``version`` is the module version in `Bazel's relaxed semver format
+  <https://bazel.build/external/module#version_format>`_.
+- The optional ``repository_url`` can be used to specify the URL of an
+  alternative registry.
+- The optional ``subpath`` can refer to a particular Bazel package in the
+  module.
+- Examples::
+
+      pkg:bazel/[email protected]
+      pkg:bazel/[email protected]
+      pkg:bazel/[email protected]?repository_url=https://example.org/bazel-registry
+      pkg:bazel/[email protected]
+      pkg:bazel/[email protected]#java/runfiles
+      pkg:bazel/[email protected]#go
