how to write a post?

To create a post, add a file to your _posts directory with the following format:

YEAR-MONTH-DAY-title.MARKUP

Where YEAR is a four-digit number, MONTH and DAY are both two-digit numbers, and MARKUP is the file extension representing the format used in the file. For example, the following are examples of valid post filenames:

2011-12-31-new-years-eve-is-awesome.md
2012-09-12-how-to-write-a-blog.md

All blog post files must begin with front matter which is typically used to set a layout or other meta data. For a simple example this can just be empty:

---
layout: post
title:  "Welcome to Jekyll!"
---

# Welcome

**Hello world**, this is my first Jekyll blog post.

I hope you like it!
ProT

Done!
