+    The C++ Ray API is currently experimental with limited support. You can track its development `here <https://github.com/ray-project/ray/milestone/17>`__ and report issues on GitHub.
+    Run the following commands to get started:
+    - Build ray from source with *bazel* as shown `here <https://docs.ray.io/en/master/development.html#building-ray-full>`__.
+    - Run `cd ray/cpp`.
+    - Run `cp dev_BUILD.bazel BUILD.bazel`.
+    - Modify `src/ray/example.cc`.
+    - Run `ray stop`.
+    - Run `bazel build //cpp:example`.
+    - Run `bazel run //cpp:example`.
+
+    .. literalinclude:: ../../cpp/src/ray/example/example.cc
+       :language: cpp
 
 You can also get started by visiting our `Tutorials <https://github.com/ray-project/tutorial>`_. For the latest wheels (nightlies), see the `installation page <installation.html>`__.
