* item two
  * item two sub-point

Renders as:

• item one
• item two
  • item two sub-point

Make it a numbered list

1. Item one
1. Item two
1. item three

Renders as:

1. Item one
2. Item two
3. Item three

You can also start a list at any number:

4. The first list number is 4.
1. The second list number is 5.
1. The third list number is 6.

Renders as:

4. The first list number is 4.
5. The second list number is 5.
6. The third list number is 6.

Make a task list by including square brackets:

- [ ] Item one
- [ ] Item two

Code Block

Creating a fixed width code block is recommended for pasting multi-line blocks of code or other text output that is easier to read with fixed width font alignment. Examples include block text snippets, ASCII tables, and log files.

This can be accomplished in one of two ways:

1. Placing 3x backtics ``` on the line directly above and directly below your code

```
this is my
code block
```

• TIP – Enter 3x backticks ```, SHIFT + ENTER, <type_your_code>, SHIFT + ENTER, and finally 3x backticks ```.

2. Indenting each line by four spaces

    this is my
    code block

^^^^ 4x spaces

Syntax Highlighting

To add syntax highlighting, type the language to be highlighted after the ``` at the beginning of the code block. Mattermost also offers four different code themes (GitHub, Solarized Dark, Solarized Light, Monokai) that can be changed in Account Settings > Display > Theme > Custom Theme > Center Channel Styles

Supported languages are: actionscript, applescript, bash, clojure, coffeescript, cpp, cs, css, d, dart, delphi, diff,

django, dockerfile, erlang, fortran, fsharp, gcode, go, groovy, handlebars, haskell, haxe, java, javascript, json,

Example:

``` go
package main
import "fmt"
func main() {
    fmt.Println("Hello, 世界")
}

Tables

Create a table by placing a dashed line under the header row and separating the columns with a pipe |. (The columns don’t need to line up exactly for it to work). Choose how to align table columns by including colons : within the header row.

| Left-Aligned  | Center Aligned  | Right Aligned |
| :------------ |:---------------:| -----:|
| Left column 1 | this text       |  $100 |
| Left column 2 | is              |   $10 |
| Left column 3 | centered        |    $1 |
