- fork the repo and make a branch for what you would like to commit
- make your changes to that branch
- use Github to make a pull request for your branch
- you may be requested to sync your branch (see github's configuring a remote for a fork and syncing a fork documentation for help with that)
bundle install --path vendor/bundle # only needed first time or after gem changes
bundle exec jekyll build
the site will then be in the _site directory.
