Basic Formatting

Bold: **Bold**

Emphasized: *Emphasized*

Strikethrough: ~~Strikethrough~~

Horizontal rules: --- (three hyphens), *** (three asterisks), or ___ (three underscores).

Headings

All heading levels (e.g. H1, H2, etc), are marked by # at the beginning of a line. For example:

H1: # Heading 1
H2: ## Heading 2
H3: ### Heading 3
H4: #### Heading 4
H5: ##### Heading 5
H6: ###### Heading 6

Links

Links can be created using several methods:

Inline link: [link text](https://example.com)
Inline with title: [link text](https://example.com "Title")
Reference link: [reference text][ref-id]
[ref-id]: https://example.com

Images

Images use the same syntax as links but with an exclamation mark at the beginning:

Inline image: ![alt text](image-url.jpg)
Reference image: ![alt text][image-ref]
[image-ref]: image-url.jpg

Lists (Ordered Lists and Unordered Lists)

Unordered lists use asterisks, plus, or minus signs:

* Item 1
* Item 2
  * Nested item
* Item 3

Ordered lists use numbers:

1. Item 1
2. Item 2
   1. Nested item
3. Item 3

Code and Syntax Highlighting

Inline code uses backticks: `code`

Code blocks are either fenced by three backticks or indented four spaces:

```
var foo = 'bar';
function baz(s) {
   return foo + ':' + s;
}
```

Blockquotes

Use > to offset text as a blockquote:

> This is a blockquote.
> It can span multiple lines.
