The site uses three Jekyll collections (defined in _config.yml):

• _pages — Main site pages (home, about, schedule, venue, etc.)
• _participants — Individual participant/speaker profiles
• _sessions — Talk and workshop entries

• Ruby 3.4+
• Bundler

bundle install

bundle exec jekyll serve

The site will be available at http://localhost:4000.

bundle exec jekyll build

Output goes to /docs (configured via destination in _config.yml).

The site is deployed via GitHub Pages, serving the static files from the /docs directory on the main branch. To deploy, build the site locally and push the updated /docs folder.
