Site configuration


###Google Tag Manager

google_tag_manager: GTM-XXXXXXX

where GTM-XXXXXXX is your Google Tag Manager Container ID. Note by default GTM tracking snippet will be also included in development. Google Tag Manager was chosen for this project as it's more flexible than Google Analytics, and it can be used to add GA to your site.


To enable Disqus comments, add your Disqus shortname to _config.yml:

  shortname: my_disqus_shortname


To use Formspree with your email address, you need to change the following:

Change email in _config.yml


Change to your email in _js/scripts (should be at the bottom of the code inside $.ajax( { function).

url: ""

You can check if it works by simply submitting the form.


Bug reports and pull requests are welcome on GitHub at This project is intended to be a safe, welcoming space for collaboration, and contributors are expected to adhere to the Contributor Covenant code of conduct.


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

Your theme is setup just like a normal Jekyll site! Check out file structure overview for details. To test your theme, run gulp and open your browser at http://localhost:3000. 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 _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-sleek.gemspec accordingly.


The theme is available as open source under the terms of the MIT License.
