## Naming and Path

Create a new file name with the format `YYYY-MM-DD-title.md` then put it into `_post` of the root directory.

## Front Matter

Basically, you need to fill the [Front Matter](https://jekyllrb.com/docs/front-matter/) as below at the top of the post:

```yaml
---
title: TITLE
date: YYYY-MM-DD HH:MM:SS +/-TTTT
categories: [TOP_CATEGORIE, SUB_CATEGORIE]
tags: [TAG]
---
```

> **Note**: The posts' ***layout*** has been set to `post` by default, so there is no need to add the variable ***layout*** in Front Matter block.

- **Categories and Tags**

    The `categories` of each post is designed to contain up to two elements, and the number of elements in `tag` can be zero or infinite.

## Table of Contents

By default, the **T**able **o**f **C**ontents (TOC) is displayed on the right panel of the post. If you want to turn it off globally, go to `_config.yml` and set the variable `toc` to `false`. If you want to turn off TOC for specific post, add the following to post's [Front Matter](https://jekyllrb.com/docs/front-matter/):

```yaml
---
toc: false
---
```


## Comments

Similar to TOC, the [Disqus](https://disqus.com/) comments is loaded by default in each post, and the global switch is defined by variable `comments` in file `_config.yml` . If you want to close the comment for specific post, add the following to the **Front Matter** of the post:

```yaml
---
comments: false
---
```


## Code Block

Markdown symbols <code class="highlighter-rouge">```</code> can easily create a code block as following examples.

```
This is a common code snippet, without syntax highlight and line number.
```

## Specific Language

Using <code class="highlighter-rouge">```Language</code> you will get code snippets with line Numbers and syntax highlight.

> **Note**: The Jekyll style `{% raw %}{%{% endraw %} highlight LANGUAGE {% raw %}%}{% endraw %}` or `{% raw %}{%{% endraw %} highlight LANGUAGE linenos {% raw %}%}{% endraw %}` are not allowed to be used in this theme !

```yaml
# Yaml code snippet
items:
    - part_no:   A4786
      descrip:   Water Bucket (Filled)
      price:     1.47
      quantity:  4
```

#### Liquid codes

If you want to display the **Liquid** snippet, surround the liquid code with `{% raw %}{%{% endraw %} raw {%raw%}%}{%endraw%}` and `{% raw %}{%{% endraw %} endraw {%raw%}%}{%endraw%}` .

{% raw %}
```liquid
{% if product.title contains 'Pack' %}
  This product's title contains the word Pack.
{% endif %}
```
{% endraw %}
