The Primer theme

Primer is a Jekyll theme for GitHub Pages. You can preview the theme to see what it looks like, or even use it today.

Usage

NOTE: Primer is now the default theme for GitHub Pages, but you can still specify the theme you're using as below.

To use the Primer theme:

1. Add the following to your site's _config.yml:

   theme: jekyll-theme-primer

2. Optionally, if you'd like to preview your site on your computer, add the following to your site's Gemfile:

   gem "github-pages", group: :jekyll_plugins

Customizing

Configuration variables

Primer will respect the following variables, if set in your site's _config.yml:

title: [The title of your site]
description: [A short description of your site's purpose]

Additionally, you may choose to set the following optional variables:

google_analytics: [Your Google Analytics tracking ID]

Stylesheet

If you'd like to add your own custom styles:

1. Create a file called /assets/css/style.scss in your site
2. Add the following content to the top of the file, exactly as shown:

   ---
   ---
   
   @import "{{ site.theme }}";

3. Add any custom CSS (or Sass, including imports) you'd like immediately after the @import line

Layouts

If you'd like to change the theme's HTML layout:

1. Copy the original template from the theme's repository
   (Pro-tip: click "raw" to make copying easier)
2. Create a file called /_layouts/default.html in your site
3. Paste the default layout content copied in the first step
4. Customize the layout as you'd like

Roadmap

See the open issues for a list of proposed features (and known issues).

Project philosophy

The Primer theme is intended to make it quick and easy for GitHub Pages users to create their first (or 100th) website. The theme should meet the vast majority of users' needs out of the box, erring on the side of simplicity rather than flexibility, and provide users the opportunity to opt-in to additional complexity if they have specific needs or wish to further customize their experience (such as adding custom CSS or modifying the default layout). It should also look great, but that goes without saying.

Previewing the theme locally

If you'd like to preview the theme locally (for example, in the process of proposing a change):

1. Clone down the theme's repository (git clone https://github.com/pages-themes/primer)
2. cd into the theme's directory
3. Run script/bootstrap to install the necessary dependencies
4. Run bundle exec jekyll serve to start the preview server
5. Visit localhost:4000 in your browser to preview the theme

Running tests

The theme contains a minimal test suite, to ensure a site with the theme would build successfully. To run the tests, simply run script/cibuild. You'll need to run script/bootstrap one before the test script will work.
