Documentation
Urho3D classes have been sparsely documented using Doxygen notation. To generate documentation into the "Docs" subdirectory, open the Doxyfile in the "Docs" subdirectory with doxywizard and click "Run doxygen" from the "Run" tab. Get Doxygen from http://www.doxygen.org & Graphviz from http://www.graphviz.org. See section "Documentation build" below on how to automate documentation generation as part of the build process.
The documentation is also available online at https://urho3d.github.io/documentation/HEAD/index.html
Documentation on how to build Urho3D: https://urho3d.github.io/documentation/HEAD/_building.html Documentation on how to use Urho3D as external library https://urho3d.github.io/documentation/HEAD/_using_library.html
Replace HEAD with a specific release version in the above links to obtain the documentation pertinent to the specified release. Alternatively, use the document-switcher in the documentation website to do so.
