This theme builds upon an amazing theme called Tale. Apart from the minor fixes to Tale, this theme is designed to make it easier to maintain a blog.
If you already have a bunch of files in *.md format, you can simply copy them to the _posts folder after forking this theme and making a few changes to _config.yml, your blog is ready to go!
