- install mkdocs via pip
- install themes:
    pip3 install mkdocs-windmill # for windmill theme
    sudo pip install mkdocs-bootswatch # for united theme
- run `julia make.jl` in `docs`
- install markdown extension for math `pip3 install pymdown-extensions`
- in terminal `mkdocs build` from `docs` directory
- `mkdocs serve` then go to address shown in browser.

#  new notes. actually, what works is:
- run `julia make.jl` in `docs`
then just `xdg-open build/index.html`
