To build a web-viewable version, you first need to download the source:

.. literalinclude:: code/build.sh

The build process is stored in the Makefile and requires Python be installed. The Makefile will create a virtualenv (venv-docs) which installs the documentation generation toolset. You may also need to install the enchant C library using your system’s package manager for the spelling checker to function properly.

To generate HTML in _build/html, run make html.

To check the formatting of the book, run make lint.

To check spelling, run make spelling. If there are additional words, names, or acronyms that are correctly spelled but not in the dictionary, please add them to the dict.txt file.

To see the other available output formats, run make.
