This cheatsheet is specifically Stackedit and Jekyll version of Github-flavored Markdown.

Github also provides some references for GitHub Flavored Markdown syntax:

• Markdown Basics
• GitHub Flavored Markdown
• Writing on GitHub

1. Table of Contents

• In StackEdit, you can insert a table of contents using the marker [TOC], then StackEdit will automaticly generate it for you.

[TOC]

• In common Markdown page, we can set the anchor using HTML syntax for quickly jumping in the page.

//set anchor in the page
<span id="jump-here"></span>
...
...
...
//set Jump link
[Jump to Headers](#jump-here)

Jump to Headers

2. Headers

# H1

## H2

### H3

#### H4

##### H5

###### H6

Alternatively, for H1 and H2, an underline-ish style:

Alt-H1
======

Alt-H2
------

H1

H2

H3

H4

H5

H6

Alt-H1

Alt-H2

3. Emphasis

Italics, with *asterisks* or _underscores_.

Bold, with **asterisks** or __underscores__.

Combined emphasis with **asterisks and _underscores_**.

Strikethrough uses two tildes. ~~Scratch this.~~

Italics, with asterisks or underscores.

Bold, with asterisks or underscores.

Combined emphasis with asterisks and underscores.

Strikethrough uses two tildes. Scratch this.

4. Lists

Manually line breaks: End a line with 2 or more spaces.

1. First ordered list item
2. Another item
    * Unordered sub-list.(indented with 'tab')
1. Actual numbers don't matter, just that it's a number
    1. Ordered sub-list
4. And another item.
    * Unordered list can use asterisks
    - Or minuses
    + Or pluses

2. Another item
   • Unordered sub-list.(indented with ‘tab’)
3. Actual numbers don’t matter, just that it’s a number
   1. Ordered sub-list
4. And another item.
   • Unordered list can use asterisks
   • Or minuses
   • Or pluses

5. Links

There are two ways to create links.

• Inline style:

An [example](http://url.com/somewhere)

An example

• Reference style:

An [example][id]
...
...
...

[id]: http://url.com/somewhere

An [example][]
...
...
...

[example]: http://url.com/somewhere

6. Images

• Inline-style:

![Example](path/to/image.jpg "Title")

Note:

• “Title” is optional here.
• Don’t forget ‘http://’ or ‘https://’ when linking to a web image.

7. Code and Syntax Highlighting

Inline `code` has `back-ticks around` it.

• Inline code has back-ticks around it.

Use ... to handle some problems that ... couldn’t.

• Blocks of code are either fenced by lines with three back-ticks ```, or are indented with four spaces. I recommend only using the fenced code blocks – they’re easier and only they support syntax highlighting – and don’t forget to leave a blank line before the block.

• In jekyll, we highlight the code with pygments, the syntax of which is like here

{********}
def foo
  puts 'foo'
end
{********}

We type in % highlight ruby % in the first ********, % endhighlight % in the second ********

def foo
  puts 'foo'
end

8. Tables

Colons can be used to align columns.

| Tables        | Are           | Cool  |
| ------------- |:-------------:| -----:|
| col 3 is      | right-aligned | $1600 |
| col 2 is      | centered      |   $12 |
| zebra stripes | are neat      |    $1 |

The outer pipes (|) are optional, and you don't need to make the raw Markdown line up prettily. You can also use inline Markdown.

Markdown | Less | Pretty
--- | --- | ---
*Still* | `renders` | **nicely**
1 | 2 | 3

Colons can be used to align columns.

9. Blockquotes

> Blockquotes are very handy in email to emulate reply text.
> This line is part of the same quote.

Quote break.

> This is a very long line that will still be quoted properly when it wraps. Oh boy let's keep writing to make sure this is long enough to actually wrap for everyone. Oh, you can *put* **Markdown** into a blockquote.

Note:

In StackEdit, the code in ''' ''' blocks will be automaticly highlighted.
But in kramdown environment, we use ``` ``` instead to write the blockquote and code block.

Blockquotes are very handy in email to emulate reply text. This line is part of the same quote.

Quote break.

This is a very long line that will still be quoted properly when it wraps. Oh boy let’s keep writing to make sure this is long enough to actually wrap for everyone. Oh, you can put Markdown into a blockquote.

10. Inline HTML

You can also use raw HTML in your Markdown, and it’ll mostly work pretty well.

<dl>
  <dt>Definition list</dt>
  <dd>Is something people use sometimes.</dd>

  <dt>Markdown in HTML</dt>
  <dd>Does *not* work **very** well. Use HTML <em>tags</em>.</dd>
</dl>

Definition list

Is something people use sometimes.

Markdown in HTML

Does *not* work **very** well. Use HTML tags.

11. Horizontal Rule

Three or more...

---

Hyphens

***

Asterisks

___

Underscores

Three or more…

Hyphens

Asterisks

Underscores

12. MathJax

Thanks to MathJax, we can use $...$(for inline) and $$...$$(for block) to render Math Symbols, like this: $A$, and Equations.

You might want to add MathJax feature to your Github Pages based on jekyll, thus this manual will be helpful. Note: As the manual says, the $...$ in-line delimiters are not used by default, you have to turn on this feature manually.
