Docs are generated using Sphinx.
Documentation is written in reStructuredText - see this link for the basic format.
In reStructuredText documents, to create the section hierarchy (mapped in HTML
<h5>) use these characters to underline headings in the
Referencing other Documentation
Other Sphinx-built documentation, both ONF and non-ONF can be linked to using Intersphinx.
You can see all link targets available on a remote Sphinx’s docs by running:
python -msphinx.ext.intersphinx http://otherdocs/objects.inv
Building the Docs
The documentation build process is stored in the
Makefile. Building docs
requires Python to be installed, and most steps will create a virtualenv

enchant C library using your system’s package manager for the
spelling checker to function properly.

Adding Images and Diagrams
There are multiple ways to add images and diagrams to the documentation. Generally, you should prefer using SVG images, as these can be scaled to any size without quality loss.
If you’re creating diagrams, there are multiple tools available. Graphviz can render inline text-based graphs definitions and diagrams within the documentation, and is best for simple diagrams.
More complex diagrams can be created in Diagrams.net/Draw.io format. When saving these diagrams, use the SVG format, and check the “Include a copy of my diagram”. This will let someone open the SVG later directly from the documentation and edit it, without any loss in functionality or quality.
