# Introduction

Markdown is a way of writing rich-text (formatted text) content using plain text formatting syntax. It is also a tool that converts the plain text formatting to HTML.

- **2004:** [John Gruber](https://daringfireball.net/projects/markdown/) developed Markdown.
- **2014:** [CommonMark](https://commonmark.org/) was established as a standard specification for Markdown to resolve inconsistencies and ambiguities in Markdown implementations. This initiative was spearheaded by [John MacFarlane](https://github.com/jgm) and backed by other Markdown enthusiasts to ensure a reliable and consistent specification.

This guide will provide you with a comprehensive understanding of the key commands in [GitHub Flavored Markdown (GFM)](https://github.github.com/gfm/), it is a strict superset of CommonMark. You can read the full article, [The Ultimate Markdown Cheat Sheet](https://towardsdatascience.com/the-ultimate-markdown-cheat-sheet-3d3976b31a0) on Medium.

# Syntax Highlighting

## Inline code

A class method is an instance method of the class object. When a new class is created, an object of type `Class` is initialized and assigned to a global constant (Mobile in this case).

You can use <kbd>command + e </kbd> on Mac or <kbd>control + e</kbd> on Windows to insert inline code.

## Code block

```
public static String monthNames[] = {"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};
```

````md
```

## Theme

### Using picture tag

The HTML `<picture>` element, along with the `prefers-color-scheme` media feature, enables you to dynamically adjust images according to the user's color scheme preference, providing options for both light and dark modes.

For example, the code snippet below demonstrates how to display a dark-themed BinaryTree logo when the user's device is set to a dark mode, and a light-themed BinaryTree logo for light mode settings:

```md
<picture>
  <source media="(prefers-color-scheme: dark)" srcset="https://github.com/lifeparticle/lifeparticle/blob/master/gh_social_dark.png">
  <source media="(prefers-color-scheme: light)" srcset="https://github.com/lifeparticle/lifeparticle/blob/master/gh_social_light.png">
  <img alt="BinaryTree" src="https://github.com/lifeparticle/lifeparticle/blob/master/gh_social_light.png" width="200">
</picture>
```
