-How to build the Doxygen HTML pages on Windows:
+# ONNX Runtime C/C++ docs source files
 
-* Install Doxygen (https://www.doxygen.nl/download.html)
-* Running from the command line:
-  * cd to (Repository Root)\docs\c_cxx
-  * Run "\Program Files\doxygen\bin\doxygen.exe" Doxyfile
-* Using the Doxygen GUI app:
-  * Launch Doxygen GUI (Doxywizard)
-  * File->Open (Repository Root)\docs\c_cxx\Doxyfile
-  * Switch to Run tab, click 'Run doxygen'
-* Generated docs are written to (Repository Root)\build\doxygen\html
+This directory contains doxygen configuration to generate the C/C++ API docs for ONNX Runtime.
 
-The generated documentation is online in the gh-pages branch of the project: https://github.com/microsoft/onnxruntime/tree/gh-pages/docs/api/c
+The actual generation is performed by a GitHub actions workflow: [publish-c-apidocs.yml](../../.github/workflows/publish-c-apidocs.yml).
+
+The workflow is currently manually triggered, and generates a PR to the gh-pages branch, for publication on https://onnxruntime.ai.
