Documentation for SMQTK is maintained at ReadtheDocs, including build instructions and examples.
Alternatively, you can build the sphinx documentation locally for the most up-to-date reference (see also: Building the Documentation):
# Navigate to the documentation root.
cd docs
# Install dependencies and build Sphinx docs.
pip install -r readthedocs-reqs.txt
make html
# Open in your favorite browser!
firefox _build/html/index.html
