 To build the libcudf HTML documentation simply run the `doxygen` command from the `cpp/doxygen` directory containing the `Doxyfile`.
+The libcudf documentation can also be built using `make docs_cudf` from the cmake build directory (e.g. `cpp/build`).
 Doxygen reads and processes all appropriate source files under the `cpp/include/` directory.

-By default, doxygen uses the `graphviz dot` tool to build diagrams of the class, namespace, and module relationships.
-If the `dot` tool cannot be found then doxygen generates output without diagrams.
-The doxygen installation page does not include instructions for downloading and installing `graphviz dot`.

 The doxygen output is intended for building documentation only for the public APIs and classes.
 For example, the output should not include documentation for `detail` or `/src` files, and these directories are excluded in the `Doxyfile` configuration.
 When published by the build/CI system, the doxygen output will appear on our external [RAPIDS web site](https://docs.rapids.ai/api/libcudf/stable/index.html).
