Building documentation

The main documentation and Python documentation is written in reStructuredText and generated by sphinx. The C++ API documentation is generated by Doxygen.

Documentation can be built on Ubuntu or macOS. Building documentation on Windows may also be possible but it is not officially tested.

If you’re building documentation on a computer without a display, please use Headless rendering, otherwise the Jupyter tutorials will fail to execute.
