This repository is the Data Carpentry template for creating websites for workshops.

  1. Do not fork this repository directly on GitHub. Instead, please follow the instructions below to create a website repository for your workshop.

  2. Please do your work in your repository's gh-pages branch, since that is what is automatically published as a website by GitHub.

  3. Once you are done, please send your repository's URL to the Data Carpentry administrator. We build the list of workshops on the main website from the data included in your index.html page. We can only do that if you customize that page correctly and send us a link to your workshop website.

  4. Please also read the notes on customizing your website and the FAQ. If you're interested in knowing more about why we do things the way we do, please check out the design notes.

  5. If you are teaching Git, please create a separate repository for your learners to practice in.

  6. If you run into problems, or have ideas about how to make this process simpler, please get in touch.

Creating a Repository

  1. Go to GitHub's importer.

  2. Click on "Check the URL". (GitHub won't import until you've done this.)

  3. Select the owner for your new repository. (This will probably be you, but may instead be an organization you belong to.)

  4. Choose a name for your workshop website repository. This name should have the form YYYY-MM-DD-site, e.g., 2015-07-01-yale.

  5. Make sure the repository is public.

  6. At this point, you should have a page like this:

    You can now click "Begin Import". When the process is done, you can click "Continue to repository" to visit your newly-created repository.

Note: some people have had intermittent errors during the import process, possibly because of the network timing out. If you experience a problem, please re-try; if the problem persists, please get in touch.

To clone your new repository, use:

git clone -b gh-pages

This is needed because the imported repository doesn't have a master branch.

Note: please do all of your work in your repository's gh-pages branch, since GitHub automatically publishes that as a website.

Customizing Your Website

  1. Go into your newly-created repository, which will be at For example, if your_username is gracehopper, and the site of the workshop is 'yale' the repository's URL will be

  2. Edit index.html to customize the list of instructors, workshop venue, etc. You can do this in the browser by clicking on it in the file view and then selecting the pencil icon in the menu bar:

    or you can clone the repository to your desktop, edit index.html there, and push your changes back to the repository.

  3. Edit _config.yml in the same way so that workshop_repo and workshop_site are the URLs of your repository and your GitHub Pages website respectively.

    Note: the URL for your website is determined automatically based on the URL for your repository. If your repository is at, its GitHub Pages website is at

  4. When you are done editing, you can preview your website. Again, if your repository is, its website will be

Editing hints are embedded in index.html, and full instructions are in This FAQ includes a few extra tips (additions are always welcome) and these notes on the background and design of this template may help as well.

Checking Your Changes

No matter how you edit index.html, you should:

  1. Check your changes by running tools/ at the command line from the root directory of your repository.

  2. Preview your changes by running tools/preview and looking at _site/index.html. To be able to preview your page locally, you must install Ruby 1.9.3 or greater plus github-pages, as described below.

For some links to work properly, particularly the link to your workshop's Eventbrite registration page, you must view _site/index.html using an HTTP server. If you have Jekyll installed, you can do this by running:

$ jekyll server -d _site

and going to http://localhost:4000.

Installing Software

In order to preview the workshop website locally on your computer, you must install the software described below.

If you aren't able to install this software (or you just can't be bothered), you can still create a website for your workshop. Every time you push a change to your website respository the live website will update automatically, so you can check your changes on the live site instead of locally.

  1. Jekyll 1.0.3

    1. Check if Ruby is installed and find its version using command line:

      $  ruby -v

      The following commands need a minimum version of 1.9.3.

    2. Install github-pages:

      $ gem install github-pages

      or if that doesn't work:

      $ gem install jekyll
      $ gem install kramdown

      We use Kramdown to translate Markdown into HTML, instead of the default Redcarpet, because Kramdown handles Markdown inside HTML blocks.

  2. The Python YAML module

    If you are using the Anaconda Python distribution, you probably already have it; if you don't, you can install it with:

    $ conda install pyyaml

    If you are using some other distribution, you can install the Python YAML module using Pip:

    $ pip install pyyaml

    and if you are on Debian Linux, you can use:

    $ apt-get install python-yaml

Setting Up a Separate Repository for Learners

If you are teaching Git, you should create a separate repository for learners to use in that lesson. You should not have them use the workshop website repository because:

  • your workshop website repository contains many files that most learners don't need to see during the lesson, and

  • you probably don't want to accidentally merge a damaging pull request from a novice Git user into your workshop's website while you are using it to teach.

You can call this repository whatever you like, and add whatever content you need to it.

Getting and Giving Help

We are committed to offering a pleasant setup experience for our learners and organizers. If you find bugs in our instructions, or would like to suggest improvements, please file an issue or mail us.
