build GitHub web resources

[lsetiawan]

We recommend leveraging many of GitHub's tools for building websites, wiki pages and tracking project work. For each hackweek we recommend:

• creating a new GitHub organization. The advantage to organizations is that it simplifies management of multiple event organizers and their permissions for creating repositories. See for example the geohackweek organization.
• use GitHub pages to generate a new landing page for your event. For recurring events, we recommend using this page as the container for the current year's events. Past events can then be archived as separate repositories.
• generate separate repositories within your organization for each tutorial. If designing tutorials for the first time, we recommend using this template adapted from Software Carpentry
• create a centralized repository for small datasets and jupyter notebooks for the tutorials.
• have an environment file for either all the tutorials combined or each tutorial. This ensures that the tutorials are self contained.
  Note that we are in the process of automating some of these steps via scripts in the pyhackweek repository
