 # This config file is meant for settings that affect your whole blog, values
 # which you are expected to set up once and rarely edit after that. If you find
 # yourself editing this file very often, consider using Jekyll's data files
 # feature for the data you need to update frequently.
 #
 # For technical reasons, this file is *NOT* reloaded automatically when you use
 # 'bundle exec jekyll serve'. If you change this file, please restart the server process.
