My website.

1. Run bundle install --path vendor/bundle to install bundles
2. To test site locally, run bundle exec jekyll serve and browse to http://localhost:4000
3. If everything looks good, run JEKYLL_ENV=production bundle exec jekyll build and copy _site to my server

Make sure you have Ruby >=2.3 and Bundler installed.
