There are three ways to install:

  • As a gem-based theme.
  • As a remote theme (GitHub Pages compatible).
  • Forking/directly copying all of the theme files into your project.

Gem-based Theme Method

Add this line to your Jekyll site's Gemfile:

gem "jekyll-theme-yat"

And add this line to your Jekyll site's _config.yml:

theme: jekyll-theme-yat

And then execute:

$ bundle

Or install it yourself as:

$ gem install jekyll-theme-yat

Remote Theme Method with GitHub Pages

Remote themes are similar to Gem-based themes, but do not require Gemfile changes or whitelisting making them ideal for sites hosted with GitHub Pages.

To install:

Add this line to your Jekyll site's Gemfile:

gem "github-pages", group: :jekyll_plugins

And add this line to your Jekyll site's _config.yml:

# theme: owner/name --> Don't forget to remove/comment the gem-based theme option
remote_theme: "jeffreytse/jekyll-theme-yat"

And then execute:

$ bundle

Forking/Cloning the project

You need to update the option of github workflow file .github/workflows/build-jekyll.yml, especially to ensure the value of jekyll_baseurl is correct.

GitHub Pages without limitation

GitHub Pages runs in safe mode and only allows a set of whitelisted plugins/themes. In other words, the third-party gems will not work normally.

To use the third-party gem in GitHub Pages without limitation:

Here is a GitHub Action named jekyll-deploy-action for Jekyll site deployment conveniently. 👍


Add or update your available layouts, includes, sass and/or assets.


To set up your environment to develop this theme, run bundle install.

Your theme is setup just like a normal Jekyll site! To test your theme, run bundle exec jekyll serve and open your browser at http://localhost:4000. This starts a Jekyll server using your theme. Add pages, documents, data, etc. like normal to test your theme's contents. As you make modifications to your theme and to your content, your site will regenerate and you should see the changes in the browser after a refresh, just like normal.

When your theme is released, only the files in _data, _layouts, _includes, _sass and assets tracked with Git will be bundled. To add a custom directory to your theme-gem, please edit the regexp in jekyll-theme-yat.gemspec accordingly.


Issues and Pull Requests are greatly appreciated. If you've never contributed to an open source project before I'm more than happy to walk you through how to create a pull request.

You can start by opening an issue describing the problem that you're looking to resolve and we'll go from there.
