Introduction
In this article, readers will learn how to write in Markdown and use it in formatting their documents.
A different range of creators can make use of Markdown. For software developers, the file with the information about your projects, like the README.md file is written in Markdown. Technical and content writers can also use Markdown to write documentation, blogs, and other write-ups.
This article helps you understand how to write in Markdown.

What is Markdown?
Markdown is a way to write and format content for the web. It uses special syntax to format documents. Writing in Markdown differs from other applications that use GUI (Graphical User Interface) to highlight and format text, like Microsoft Word, and Google Docs.
Some text editors provide WYSIWYG (What You See Is What You Get) features that render and display the Markdown formatted text as you edit them, like Visual Studio Code, Notepad++, Ghostwriter, etc. These text editors might require an extension/plugin to display Markdown.
The file extension for markdown is .md or .markdown. Say you have a file named my_file, to make it a Markdown file, you save it as my_file.md or my_file.markdown.
Markdown was created by John Gruber in 2004.
Formatting in Markdown
Special characters are used to format Markdown files, i.e. making text italics, bold , and so on. These special characters are highlighted below:
TO SPARK YOUR INTEREST, THIS ARTICLE WAS WRITTEN IN MARKDOWN.
NOTE: The rendered Markdown is shown after every code block.
Headers
To indicate a header in Markdown, begin the line with a hash (#) sign. There are six levels of headers in Markdown, and the number of # signs beginning the line marks the level of the header. Each header must be separated with blank lines.
# Header LEVEL 1
## Header LEVEL 2
### Header LEVEL 3
#### Header LEVEL 4
##### Header LEVEL 5
###### Header LEVEL 6

Paragraphs
To write paragraphs in Markdown, you separate each paragraph with a blank line. Some Markdown renderers require that you end each paragraph with two spaces ([][]) to mark the end of the paragraph, and to also indicate blank lines, like GitHub Flavored Markdown.
This is a paragraph,
and this is part of the same paragraph.
[BLANK LINE]
This is another paragraph.[][]
This is yet another paragraph.[][]
[][]
And this is also another paragraph.
RENDERED OUTPUT
[]in the example code above represents a space from pressing the " SPACEBAR" key
Bold
To bolden a text, surround the text with two asterisks (**) or*two underscores* (__). Be consistent with whichever you choose.
Surround text with **two asterisks** or __two underscores__ to format as bold.
RENDERED OUTPUT
Italics
To display text as italics, surround the text with one asterisk (*) or one underscore (_). Whichever you decide to use, try to be consistent with it.
Surround text with *asterisk* or _underscore_ to format as italics.

Lists
Lists are used to present text in steps. They are usually separated by blank lines for readability sake. There are two main types of lists as explained below:
Ordered Lists
Lists are presented in an order when the next step cannot be done before the previous step. For example, to put on your trainers when you want to go for a run, you don't wear your shoes before wearing your socks, it has to be done the other way around. To indicate an ordered list, begin each line with a number (1, 2, 3, etc) and a period (.) sign.
Follow this routine when exercising:
1. Warm-up
2. Low-intensity exercises
3. High-intensity exercises
4. Warm-down
RENDERED OUTPUT
Unordered Lists
Lists that don't require any particular order are labelled unordered. For example, when shopping for groceries, you can decide to get the third, or seventh item on the list provided you are on the aisle where the item is displayed before picking up the first item. To display an unordered list, begin each line with an asterisk (*), a dash (-), or a plus sign (+).
REMEMBER : Be consistent with whichever format you choose.
Provisions List
* Peanut Butter
* Cookies
* Cereal
Body Care List
- Hair Cream
- Body Cream
- Deodorant
Cloth List
+ Shirts
+ Jeans
+ Socks
RENDERED OUTPUT
Lists can also be nested in lists. To do this, indent the nested list by at least 4 spaces or 1 tab.
How to:
* Develop a program
1. Think out the algorithm
2. Write the pseudocode
3. Code the program
* Prepare a cereal
* Get the cereal
* Get the bowl and cutlery
* Pour the milk
* Pour the cereal
* Add sweeteners
RENDERED OUTPUT
Note how you can get the bowl and cutlery before the cereal, or pour the cereal before the milk, for unordered lists.
Code
Code is highlighted and formatted differently from every other text. It is mainly used to display programming languages, but can also be used to display special text. The two ways to display text as code are shown below:
Inline Code
To display code inline, that is, without breaking the flow of the document, surround the code with backticks (`).
To display output in Python, use the `print()` function.
RENDERED OUTPUT
Multi-line Code
To display code in more than one line, as a block, surround the lines with three backticks or three tilde (~~~) signs. To format the code as a specific programming language, or as a text, add the language file extension after the first three backticks or tilde signs.
Displaying output in Python
```py
print("Hello, world!")
```

Blockquotes
Blockquotes are displayed in a special way to get the reader's attention. It is usually used to indicate important information. To highlight a blockquote, begin each line with the greater than sign (>). Blank lines in blockquotes also begin with >.
Here are two famous quotes:
> The greatest glory in living lies not in never falling, but in rising
> every time we fall.[][]
> \- Nelson Mandela
>
> The way to get started is to quit talking and begin doing.[][]
> \- Walt Disney
RENDERED OUTPUT
Note the two spaces after the quote to end the paragraph, and the backslash "\" (explained later in this article) used here to prevent the text from becoming a list within the blockquote.
Links
Links are used to direct users to another location, like another page on the website/document, or another website/document entirely. Links are formatted in two ways:
Inline Links
For inline links, the links are shown side-by-side with the text when writing Markdown. To create an inline link, surround the link text with square brackets [], and then follow up with the link surrounded with parentheses (). There should be no space between the square brackets and parentheses.
This is a link to my very [first article](https://ogagaonuta.hashnode.dev/python-need-to-know-for-beginners)
Clicking on the link text will now point you to the specified link as shown below:
RENDERED OUTPUT
Reference Links
For reference links, a tag name is placed side-by-side with the text. This tag name then points to the link somewhere else in the document. This makes the document readable, by separating the link(s) from the text. It also helps when editing as you only have to correct the link in one place, rather than going through the whole document and correcting the link in several places.
To create a reference link, surround the link text with square brackets [], and then follow up with the tag name surrounded in square brackets. There should be no space between the square brackets and the tag name. For a multi-word tag name, use underscores or dashes as a separator.
The tag name can now be pointed to the link anywhere else in the document by specifying the tag name in square brackets, followed by a colon (:), a space, and then the link, all on its line. This is mostly placed at the end of the document.

Images
Images can also be displayed in Markdown. Images are formatted the same way as links, with the one difference of beginning each image with an exclamation mark (!). The link text is replaced with an alternate text for the image, and the link itself is replaced with a link to the image, either stored locally on your computer or hosted online. As links, there are two ways to format images:
Inline Images
To display an image inline, you begin with an exclamation mark (!), and then follow the same syntax as the inline links described above.
This is an image of the **Bash _Shebang_**.
RENDERED OUTPUT
Reference Images
To display an image as a reference, you begin with an exclamation mark (!), and then follow the same syntax as the reference links described above.
My present profile picture.
![profile picture][prof-pic]
[prof-pic]: ./images/profile_picture.png
RENDERED OUTPUT
Table
A table is a visual aid arranging elements in rows and columns. Markdown is also able to create tables by using the pipe (|) character. Each column is separated by the pipe character, and each row is placed on its line. To separate a header row from the body row, you create a row with each column filled with dashes (-)
Columns can be aligned by placing colons (:) on the row separating the header and body. By default, columns are left aligned. Put the colons:
on the left for left alignment
on the right for right alignment
on both sides for centre alignment
The Logic **AND** Table
| A | B | A AND B |
| :---- | :---- | :-----: |
| True | True | True |
| True | False | False |
| False | True | False |
| False | False | False |
RENDERED OUTPUT
The "Escape Character"
The escape character is used to prevent the character which follows it from executing its special meaning. It removes the formatting of the character and displays it as plain. The escape character is the backslash (\), and it comes in handy when writing in Markdown.
\* is used to begin a list item in Markdown.
\- is also used, it's just based on preference.
The **asterisk \*** is used to format text as bold.
To escape a backtick in an inline code, surround it with two backticks `` ` ``.
The escape character can also escape a backtick, e.g. \`print()\` instead of
`print()`.
RENDERED OUTPUT
Note the use of backticks to escape another backtick. This is a special case.
