In `circuitpython/`, build the docs:
sphinx-build -v -b html . _build/html
make html
You'll find the index page at `_build/html/index.html`.
### More flexibility
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.
