There's nothing special about this site: it's just static HTML and CSS. If you need to edit something, you can go ahead and change the HTML directly. At some point this will change to jekyll (either as a learning exercise for Ruby/jekyll or for CrashCourse next year to improve maintainability).

• index.html
  • Main landing page
• CNAME
  • This site is hosted on GitHub Pages, so including this file tells the world that this site will be accessed from crashcourse.scottylabs.org
• assets/
  • css/
    • Contains Bootstrap source code and extra modifications
  • docs/
    • Used for storing materials from presentations and other docs
  • img/
    • Contains the images used for styling and content
  • js
    • Okay I lied: this site has more than jusy HTML and CSS. This Javascript is only used for the navbar on the mobile responsive site.
• register/
  • Landing page for event registration
• schedule/
  • Landing page for event schedule
• workshops
  • Each course description page is enclosed by a subdirectory within this folder. The template with blanks in all appropriate places (a prime candidate for use with jekyll!) is located within the intro-to-html-css foler

Because this site is hosted on GitHub Pages as a project page (not a user/organization page), all changes must be pushed to the branch gh-pages. This can get annoying because there is no way to delete the master branch, so you should probably update your .git/config file to look like this:

[core]
  repositoryformatversion = 0
  filemode = true
  bare = false
  logallrefupdates = true
  ignorecase = true
  precomposeunicode = false
[remote "origin"]
  url = https://github.com/ScottyLabs/crashcourse-website.git
  fetch = +refs/heads/*:refs/remotes/origin/*
  push = +refs/heads/master:refs/heads/gh-pages
  push = +refs/heads/master:refs/heads/master
[branch "master"]
  remote = origin
  merge = refs/heads/master
[branch "gh-pages"]
  remote = origin
  merge = refs/heads/gh-pages

Note how the last two lines of [remote "origin"] make it so that every time you type

$ git push

you push the same code to both branches. This makes sure that both branches are always in sync.
