The Markdown syntax is how we format text. A markdown file ends with the .md or .markdown extension. Before we get into it, let's make a new repository on GitHub.

After you login, click on the "New" green button on the left to create a new repository.

Now fill in the name and details about your new repo. Ensure "Initialize this repository with a README.MD" is checked.
Now you will be greeted with your new repo! Click on the "README.MD" file
Now click on the edit button
You'll be greeted with a screen similar to this where you can input your text.
There's also the preview section which shows you what has been changed, removed and added in your file. We will go more about diffs in a later chapter. For now, let's learn markdown!

Heading

Headings range from 1 to 5, with 1 being the largest and 5 the smallest. To write a line of heading, we add # before the text.

Markdown Output
# Heading 1

Heading 1
## Heading 2

Heading 2
### Heading 3

Heading 3
#### Heading 4

Heading 4
##### Heading 5
Heading 5

Emphasis

To emphasize text, we can use bold, italics or strike.

**bold** bold
_italics_ italics
~strike~ strike

Lists

Markdown allows you to have three kinds of list.

Ordered Lists

Indents and Combination

Ordered and Unordered lists can be combined, along with indentation with tabs to create nested lists.

Code

There are two ways to mark a block of text as code in markdown.

Markdown Output
`single line` single line
```
multi
line
code
```		 
multi
line

Table

Creating tables in markdown can get confusing (and irritating) at times, so it's much easier to use a service like Markdown Table Generator and paste in the code.
