Steps to making this github pages site:

Install and activate the environment in the yaml file
Create core files with pelican-quickstart, including YES to github pages
Link to Flex pelican theme. It can be downloaded here https://github.com/alexandrevicenzi/flex
Most configuration is in pelicanconf. Most important is the SITEURL. I have configured this to be optionally read from a json file, so that you can build the site for different urls by making a local secrets.json file
Content as Markdown files
In git, do all editing on source branch
Test site with make html && make serve
Push to github with make github this will push content to master to make it a pages site
