You can add additional posts in the browser on GitHub.com too! Just hit the + icon in /_posts/ to create new content.

Just make sure to include the front-matter block at the top of each new blog post and make sure the post’s filename is in this format: year-month-day-title.md

问题现象：

将一篇md文件，添加到_posts目录，在GitHub Page页面一直看不到

原因：

md文件的格式没有按照year-month-day-title.md的格式，day和title之间用了下划线，而不是中横线。
