Markdown syntax

Markdown is a lightweight markup language with plain text formatting syntax. Below is the syntax cheatsheet for quick reference to get things done with Markdown.

Headers

Heading 1 - Markup :  

# Heading 1
# Heading 1 #
============= (below H1 text)

Heading 2 - Markup :  

## Heading 2
## Heading 2 ##

Heading 3 - Markup :  

### Heading 3
### Heading 3 ###

Heading 4 - Markup :  

#### Heading 4
#### Heading 4 ####

Heading 5 - Markup :  

##### Heading 5
##### Heading 5 #####

Emphasis

Common text

Markup :  Common text

Emphasized text

Markup :  _Emphasized text_ or *Emphasized text*

Strikethrough text

Markup :  ~~Strikethrough text~~

Strong text

Markup :  __Strong text__ or **Strong text**

Strong emphasized text

Markup :  ___Strong emphasized text___ or ***Strong emphasized text***
Colored Text
Markup: <span style="color:red">**No**</span>

Backslash Escapes

Markdown allows you to use backslash escapes to generate literal characters which would otherwise have special meaning in Markdown’s formatting syntax. For example, if you wanted to surround a word with literal asterisks (instead of an HTML tag), you can use backslashes before the asterisks, like this

\*literal asterisks\*

Markdown provides backslash escapes for the following characters:

\   backslash
`   backtick
*   asterisk
_   underscore
{}  curly braces
[]  square brackets
()  parentheses
#   hash mark
+   plus sign
-   minus sign (hyphen)
.   dot
!   exclamation mark

Named Link and http://2much2learn.com or http://2much2learn.com/

Markup :  

[Named Link](http://2much2learn.com "Named link title") 
http://2much2learn.com
<http://2much2learn.com>
<a href="http://2much2learn.com" target="_blank">2 much 2 learn</a>

If you have headers in the markdown files, you can directly link them in the file.

Markdown Header

# Heading 1

this will generate an implicit id #heading-1 (replace internal spaces with hyphens and make lowercase).

To navigate to this id, you can create the link like this:

heading-1

Markup: [heading-1](#heading-1 "Goto heading-1")

Tables

Table, like this one :

First HeaderSecond Header
Content CellContent Cell
Content CellContent Cell
Markdown:

First Header  | Second Header
------------- | -------------
Content Cell  | Content Cell
Content Cell  | Content Cell
OptionDescription
datapath to data files to supply the data that will be passed into templates.
engineengine to be used for processing templates. Handlebars is the default.
extextension to be used for dest files.
markdown:

| Option | Description                                                               |

| ext    | extension to be used for dest files.                                      |

Each column can be aligned left, right, or center. The alignment is set by using a pattern of dashes and a colon separated by spaces and pipes.

  • To left-align a column, put a colon to the left of two dashes :--.
  • To right-align, put a colon to the right of two dashes --:.
  • To center-align, surround a dash with two colons :-:.

Right aligned columns

Mathematical expressions

You can render LaTeX mathematical expressions using katex-math

The Gamma function satisfying $\Gamma(n) = (n-1)!\quad\forall n\in\mathbb N$ is via the Euler integral

$$ \Gamma(z) = \int_0^\infty t^{z-1}e^{-t}dt\,. $$

Markup:

\Gamma(z) = \int_0^\infty t^{z-1}e^{-t}dt\,.

UML diagrams

Generation of diagrams and flowcharts from text in a similar manner as markdown is achieved using mermaid.

You can render UML diagrams, this will produce a sequence diagram:

AliceBobJohnHello Bob, how are you?How about you John?I am good thanks!I am good thanks!Bob thinks a longlong time, so longthat the text doesnot fit on a row.Checking with John...Yes... John, how are you?AliceBobJohn
Markup:

```mermaid
sequenceDiagram
Alice ->> Bob: Hello Bob, how are you?
Bob-->>John: How about you John?
Bob--x Alice: I am good thanks!
Bob-x John: I am good thanks!
Note right of John: Bob thinks a long<br/>long time, so long<br/>that the text does<br/>not fit on a row.

Bob-->Alice: Checking with John...
Alice->John: Yes... John, how are you?
```

And this will produce a flow chart:

Link text
Square Rect
Circle
Round Rect
Rhombus
Markup:

```mermaid
graph LR
A[Square Rect] -- Link text --> B((Circle))
A --> C(Round Rect)
B --> D{Rhombus}
C --> D
```
