+-----
+``bazel`` for Bazel modules:
+
+- The default repository ("registry") is ``https://bcr.bazel.build``, the
+  Bazel Central Registry (BCR).
+- The ``name`` is the module name. It must be lowercased.
+- 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, with any trailing forward slashes removed.
+- The optional ``subpath`` can name a particular Bazel target in the module via
+  a label with the leading double slash (``//``) removed and canonicalized by
+  omitting the target name if it is equal to the name of the containing package.
+- 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]#toolchains:singlejar
+      pkg:bazel/[email protected]#go
