Simon Prickett's GitHub pages site. Check out the live site at https://simonprickett.dev/.
Jekyll and the Ruby ecosystem are pretty brittle and hard to manage, so just use Docker to run this locally:
docker-compose up
Then wait until you see:
simonprickettgithubio-jekyll-1 | Server address: http://0.0.0.0:4000/
simonprickettgithubio-jekyll-1 | Server running... press ctrl-c to stop.
The site should then be available at http://localhost:4000.
Jekyll watches for changes and will restart whenever you save an existing file or add new ones.
