The latest documentation can be found at: http://circuitpython.readthedocs.io/en/latest/

The documentation you see there is generated from the files in the whole tree: https://github.com/adafruit/circuitpython/tree/main

If you're making changes to the documentation, you should build the documentation locally so that you can preview your changes.

Install the necessary packages, preferably in a virtualenv, in circuitpython/:

pip install -r requirements-doc.txt

In circuitpython/, build the docs:

make html

You'll find the index page at _build/html/index.html.

Running make by itself will list out the multiple doc generating commands available.

All commands will, by default, run with -E (forces a rebuild from scratch of docs) and -v (verbosity level 1). This can be customized as desired:

# will turn OFF the force rebuild
make html FORCE=

# will turn OFF the verbosity
make html VERBOSE=

# will turn OFF the force rebuild and make it doubly verbose when running
make html FORCE= VERBOSE="-v -v"

You can also pass other options to sphinx by using SPHINXOPTS.

make html SPHINXOPTS="-T"

For more flexibility and customization, take a look at the Makefile for all variables you can pass in and overwrite.
