To create a new post, you can create a new markdown file inside the _posts directory by following the recommended file naming 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
Post requires front matter, everything in between the first and second — are part of the YAML Front Matter, and everything after the second — will be rendered with Markdown and show up as “Content”. The following is a post file with different configurations you can add as example:
---
layout: post
title: How To Travel On Low Budget
---
You can rebuild the site in many different ways, but the most common way is to run bundle exec jekyll serve, which launches a web server and auto-regenerates your site when a file is updated.
To keep things more organized, add post images to /assets/posts/ directory, and add theme images to /assets/img/ directory.
