TIPs

• Install Ruby, Jekyll to run locally. Or maybe you can just install gem install github-pages – I did not try this.
• The site shows content of index.html, which contains posts and a visitor counter.
• Files you will need to modify
  • index.html
  • _layouts/default.html
  • _config.yml
  • style.scss
  • _posts/
• Post file name should have format year-month-date-title.md. BTW, the date should not be in the future.
• Newer post (with newer date naming) will be displayed ahead of older post in index.html
• To force new line in markdown, you can end the former line with more than one empty space. In other words,

  line1  \n
  line2
