Use either reStructuredText, Markdown or Jupyter Notebooks. To create an empty post:
$ nikola new_post -f markdown # default is .rst if not specified
Note that for Jupyter notebook posts the post metadata (title, author, slug, date) goes in the notebook metadata as documented here. Jupyter Lab does not have a metadata editor yet - either use Jupyter notebook, install https://github.com/yuvipanda/jupyterlab-nbmetadata (although that did not work in a first test), or edit the metadata by hand.
To not show the whole post but only the first bit and then read more ..., use <!-- TEASER_END --> (either in plain Markdown or in a Markdown cell in a notebook).
To set up a development environment: in a new conda env or virtualenv:
$ pip install "nikola[extras]"
$ nikola theme -i maupassant
Configuration file for the site is conf.py.

Submit pull requests first, those get run on CircleCI where the new site can be checked (stored in Artifacts). On merge the site will get deployed to https://labs.quansight.org
