To customize the index page, edit

To add a new post, create a .md file in the markdown folder. It will automatically be added to the listing on the index page.

For more advanced customization, you can edit index.html to further customize the index page, blog.html to customize the posts, and style.css to customize the stylesheet. All pages are generated based off these three files.
