Markdown is a simple markup language that enables you to easily format text using a plain text editor. Here is a quick guide to the most common Markdown syntax:

You can create headings by using one to six hash symbols (#). The number of hash symbols corresponds to the heading level. For example:

Code

# Heading 1
## Heading 2
### Heading 3

Result

You can emphasize text in three ways:

• Italic: Surround the text with a single asterisk or underscore.
• Bold: Surround the text with two asterisks or underscores.
• Bold and italic: Surround the text with three asterisks or underscores.

You can also strikethrough text by surrounding it with two tildes (~~).

Code

*italic*
**bold**
***bold and italic***
~~strikethrough~~

Result italic bold bold and italic strikethrough

You can create ordered and unordered lists. For unordered lists, use a hyphen (-), plus sign (+), or asterisk (*) as the bullet point. For ordered lists, use numbers. For example:

Code

- Item 1
- Item 2
  - Subitem 1
  - Subitem 2

Result

• Item 1
• Item 2
  • Subitem 1
  • Subitem 2

Code

1. Item 1
2. Item 2
   1. Subitem 1
   2. Subitem 2

Result

1. Item 1
2. Item 2
   1. Subitem 1
   2. Subitem 2

You can create links by surrounding the link text with square brackets ([]) and the link URL with parentheses (()). For example:

Code

[Link text](https://github.com/JackGraymer/Markdown-Cheatsheet)

Result Link text

You can add images by using an exclamation mark (!) followed by square brackets for alt text and parentheses for the image URL. For example:

Code

![Alt text](https://picsum.photos/420)

Result

You can indicate inline code by surrounding the code with backticks (`). To create a code block, use three backticks and specify the language (optional). For example:

Code

`code`

Result code

Code

console.log('Hello world!');

Result

console.log('Hello world!');

You can create blockquotes by using a greater than symbol (>). For example:

Code

> This is a blockquote.

Result

This is a blockquote.

You can create a horizontal rule by using three or more hyphens (---), asterisks (***), or underscores (___).

Code

---

You can create tables by using vertical bars (|) and hyphens (-) to separate columns and rows, respectively. Also the text can be justified.
For example:

Code

| Name | Age | Gender |
|:-----|:---:|-------:|
| Left | Center | Right |
| Jane | 30  | Female |
| Bob  | 40  | Male   |

Result

You can strikethrough text by enclosing it in two tilde symbols (~~). For example:

This is ~~strikethrough~~ text.

Result This is strikethrough text.

You can create task lists by using the hyphen (-) or asterisk (*) character with a space, followed by [ ] or [x] inside the square brackets to indicate whether the task is incomplete or complete, respectively. For example:

- [x] Completed task
- [ ] Incomplete task

Result

• Completed task
• Incomplete task

You can use emojis in Markdown by typing a colon (:) followed by the emoji name and another colon. For example:

:thumbsup:

Result 👍
