NYCDH Week Workshop: Publishing Sites with GitHub Pages

06 February 2018


1: GitHub is a place for Open Source projects, which are stored in repositories.

2: A fork is a copy of a repository that is all your own and helps you track changes.

3: Markdown is an easy to use markup schema for designating headings, lists, links, images and more.

4: Jekyll is software for creating static sites that GitHub can run for you. It is responsible for converting your markdown into your site’s HTML files.

5: Liquid is a templating engine that helps you work with your site’s data and content in more dynamic ways than Markdown. Jekyll also converts liquid into HTML files for you.


Table of Contents

  1. Set up a GitHub Account
  2. Fork the sample site into your account
  3. Set up your GitHub domain
  4. View your site
  5. Edit a post
  6. Add a new page


Step 1: Set up a GitHub Account

Visit and add your information. Choose the Free/Public plan, then activate your account by checking your email for the registration link.

Note: Your username will also be part of your site’s public URL, so choose one you can live with!

Step 2: Fork the sample site into your account

Visit the base site repository in a new tab and click on the fork button near the top right corner.

This creates a fork (i.e. a diverging copy) of our base site for you to use and change however you want.

Step 3: Set up your GitHub domain

Before we start changing how things look, we’ll need to see your site live at your own domain. Click on the Settings tab and rename your repository to reflect your domain. This will be:

For example, if your GitHub username is bharkonnen, your site will be

Return back to the page with your files and find _config.yml. Click on it, then click the pencil button to edit. Replace the baseurl value with empty single quotes: ''. (This will serve your site at your domain instead of

Next, fill in other information (e.g. title, description, and username) as you like. Scroll down and click “Commit changes” when you are ready.

You can always change these later, so don’t worry!

Step 4: View your site

Open up a new tab, and navigate to your domain. It may take a minute or so, but should look like something like this:

Step 5: Edit a post

While still on your live site, click on “Writing My Own Post.” (It should be at

Open the Markdown Cheatsheet in another tab. And in one more tab, open your site repository on GitHub, navigate into _posts, open, and click edit.

Skim through the Markdown Cheatsheet and rewrite the contents of the post with headers, lists, and links. Commit the edits and refresh the live post to see your changes.

Note: Jekyll is very picky about post titles and dates. If you want to change them, make sure you keep the same date format! Titles cannot have : characters unless you wrap the entire title in quotes (title: "My Tile: My Subtitle"). Lastly change the file name (up top) to reflect your new title and date.

Bonus: You can use StackEdit to preview what your Markdown will look like before editing your files, if you like!

Step 6: Add a new page

Now that we’ve edited an existing post with Markdown, we can add a brand new page with text and images. Navigate to the home of your site repository on GitHub, and click “Create New File”.

Enter the name of your file up top. It cannot have spaces or special characters, must be lowercase, and must end in .md (for Markdown).



Add metadata to the top of your file, between two lines with three hypthens, like so:

layout: page
title: Your Title

Underneath the metadata, add info to your page just like with the post. This time, try to add at least one image! The syntax for an image is:


Advanced: Liquid for Jekyll functionality

Congrats! If you’re reading this, you’re likely ahead of the game. Now is a good time to dive deeper into Jekyll and its templating engine Liquid.

Liquid is a kind of pseudo-code that lets you access information about your site, its pages, posts, and more to display on your site.

For example, Liquid is powering your current home page and how it shows posts. Under the hood, it looks something like this:

{% for post in site.posts %}

   <a href="{{ post.url | prepend: site.baseurl }}">{{ post.title }}</a>

 <a href="{{ post.url | prepend: site.baseurl }}">
  {{ | date: "%b %-d, %Y" }}

 <p>{{ post.content | strip_html | truncatewords:30 }}</p>

{% endfor %}

This constructs a post loop so that each of your posts automatically shows up and has the same type of information displayed in the same way.

Try adding your post’s categories to one of your posts with liquid. You’ll need to replace/add categories in the metadata of your post (in brackets [ ] and separated by commas), and then add liquid to the body of your post. To get you started, you’ll set up the loop with:

{% for category in page.categories %}
 {{ category }}
{% endfor %}

Advanced: Change your theme

The following link has a list of themes that are currently supported by GitHub Pages through the remote_theme variable in _config.yml: You can peruse to find one you like and, when you’re ready, replace

remote_theme:     broccolini/athena

with the theme you want, with the structure username/repository-name. (e.g. mmistakes/minimal-mistakes )
