How to create a blog with GitHub Pages and Jekyll Part 3

How to create you first Jekyll post

Create a _posts folder at the root of your repository
Create a file matching the following pattern YEAR-MONTH-DAY-title.MARKUP, eg 2016-06-11-this-is-my-first-post.md. md means Markdown, which is what’s used on GitHub
Starts that file with a Front Matter block, like this-is-my-first-post
```
---
the front matter content
---
```
The front matter content is following the YAML format, which basically means something like
```
key1: value1
key2: value2
```
In our case, we’ll use the following
```
---
layout: post
title: The title of my awesome post!
---
```
Below, simply write your content! Markdown is a pretty simple format to use. You can check https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet for samples
Save it. If you haven’t already done so, run jekyll serve. This will generate the corresponding html file under _site. Head over to http://127.0.0.1:4000/year/month/day/name-of-your-awesome-post.html (or whatever address and port number is displayed by the jekyll serve command). Note that the extension will be html.

Now you’ll probably noticed that your post is not really sexy…so head over to the next part to fix that.
