    • its easier to track if everything related to your progress is in one repository

Creating a website

  • The cherry on the cake for today
  • Create a new repo under your username at github called yourgithubusername.github.io
  • Make a local version of it (clone)
    • Pay attention not to clone inside another git repo!
  • Create an index.html file with content, images and styling or use the ones from first day
  • push!
  • see your website at http://githubusername.github.io
  • its another repo, so you should include links in your main README.md
    • about the website
    • and the repository as well
