Building Jekyll

This site is built using Jekyll. You don't need to know or even run jekyll to contribute - you can just edit and commit the markdown files, but if you want to run a local copy it's fairly simple:

cd dataschool/dataschool
bundle install --path vendor/bundle
bundle exec jekyll serve --watch

It will then be available at http://localhost:4000

Note - do use port 4000 and "localhost" vs otherwise SQLBox will not work for you on your localhost.


There are 3 main objects (jekyll calls them collections) in DataSchool:

  • People (_people)
  • Books (_books)
  • Chapters (_chapters)

The content for all of the books is in _chapters folder, organized by book.
