Use the Gem with Jekyll
This theme requires Jekyll 3.9 to be compatible with GitHub Pages.
Add this line to your Jekyll site’s Gemfile:
gem "bulma-simple-theme"
And add this line to your Jekyll site’s _config.yml:
theme: bulma-simple-theme
And then execute:
$ bundle
Or install it yourself as:
$ gem install bulma-simple-theme
GitHub Pages
If you are deploying to GitHub pages, then you can also install the GitHub Pages gem and use remote_theme instead of theme in your _config.yml.
# With GitHub Pages Gem
remote_theme: ianfab/bulma-simple-theme
