31+
32+Most of the sphinx requirements are installed from :origin:`setup.py` and the
33+docs can be build from scratch with ``make docs``. For better math and image
34+processing additional packages are needed. The XeTeX_ needed not only for PDF
35+creation, its also needed for :ref:`math` when HTML output is build.
36+
37+To be able to do :ref:`sphinx:math-support` without CDNs, the math are rendered
38+as images (``sphinx.ext.imgmath`` extension). If your docs build (``make
39+docs``) shows warnings like this::
40+
41+ WARNING: dot(1) not found, for better output quality install \
42+ graphviz from http://www.graphviz.org
43+ ..
44+ WARNING: LaTeX command 'latex' cannot be run (needed for math \
45+ display), check the imgmath_latex setting
46+
47+you need to install additional packages on your build host, to get better HTML
