To build, you need a recent version of python and pip. One time only in this directory, set up a python version environment:
python -m venv venv
The .gitignore file for this project is already set up to ignore the ./venv directory just created.
All installations will be made in this virtual environment. Activate the environment with:
source ./venv/bin/activate
Then run:
pip install mkdocs-material
pip install mkdocs-graphviz
mkdocs serve
Mkdocs will run a server you can visit in a web browser.
On subsequent sessions, run source ./venv/bin/activate to activate the virtual python environment.
Then mkdocs serve to get a preview of the site.
