This is a “quick” how-to guide for using Discourse forum/community software. It contains a majority of the common features avialble to users/content editors, but may not have complete coverage of the featureset. If anyone sees anything to add or correct, feel free to comment. If you’d like to learn more about the Discourse Editor’s syntax take a look at the commonmark (a flavor of markdown) docs for more info.

Most of the time you’d want to use the editor bar or hotkey crtl+k, but the basic format is [link text](https://digikey.com) which will give you an example link that looks like this: link text

Note - Easier Editing with Links
Having long URLs intermingled in your editor can sometimes make it a pain so you can also offset the links using the syntax in the example below. Note you must have a blank line above the reference and the reference id can be any number, text, or punctuation.

Copy to clipboard

This paragraph is much easier to read in the [editor][1] because you can
[include][dklink] the links below the paragraph text or at the bottom of the page.

## Images

Adding images is quite easy, if there’s an image in your clipboard, just paste it in, the forum will automatically upload the image and fill in the appropriate syntax to make the image appear. If you are linking an image which is already on the web, use the following syntax. ![title text](/uploads/default/original/2X/f/f2efd3f9c7eeb0a6f1ec321baa7a8d715465e47a.jpg) Result: You can also upload images directly using the editor button

#### Image Sizing

If you would like to resize a large image to a smaller image use the following syntax.

Copy to clipboard

![Original|200x200](/uploads/default/original/2X/f/fa4db02364adfc69ad5e0e63ecbe4784b0d25b19.jpg)


Original Resized 50% By Pixels

## Text Formatting

For bold, italics and strike-through use the editor buttons or directly type the markdown:

Copy to clipboard

**bold word** or __bold word__
*italicized word* or _italicized word_
_combo of **bold** and **italic**_
~~strike-through word~~


bold word or bold word
italicized word or italicized word
combo of bold and italic
strike-through word

Alternatively, there’s some BBCode sytnax that a person can use
[b]like this[/b] like this
[i]or this[/i] or this
[u]underline[/u] underline

Font color is not natively supported, but there is a BBCode plugin that will allow for changes in font color.
One can also have some choice to change fonts or colors using the LaTeX-based mathjax plugin covered in the mathjax section of this guide. $\color{red}{red text}$ redtext

## Lists

You can use the editor buttons for ordered or unordered lists.

Copy to clipboard

1. First ordered list item
2. second list item
* sub-lists are offset by three spaces
1. Specific numbers
1. don't matter they will auto increment
1. auto increment

* unordered lists
* are also possible

1. First ordered list item
2. Explicit second list item
• sub-lists are offset by three spaces
1. Specific numbers
2. don’t matter they will auto increment
3. auto increment
• unordered lists
• are also possible

## Code Formatting

### Inline code formatting

Surround a section of code with backticks () inline code formatting. **Typing:** var x = 10;**Results in:**var x = 10;This can also be done as var x = 10; inline.

Present entire line as code by prefixing four (4) spaces (an extra newline before this)
Typing :

 var this = “is a line”;


Results in :

Copy to clipboard

var this = "is a line";


### Multi-Line Blocks of Code

Surrounding code with three backticks  will allow for code to span multiple lines
Typing:

function foo(bar){
return bar+1;
}


Results in:

Copy to clipboard

function foo(bar){
return bar+1;
}


Syntax Highlighting
The code block will try to automatically choose a style for code, but you can explicitly call out the desired formatting.

function foo(bar){
return bar+1;
}


Results in:

Copy to clipboard

function foo(bar){
return bar+1;
}


## Tables

Tables are second class citizens in Discourse, some of the formatting features and niceties work and some don’t.

Protip - The easiest way to get a table into discourse is to start a table in an spreadsheet, then copy & paste that table into the editor window. Discourse natively handles the format change and makes creating a table much easier. Excel and Google Sheets work great using this method.

A markdown table in Discourse needs at least the first two lines to exist:

Copy to clipboard

|Color|Weight|Height|
|-|-|-|
|red|12|160|
|green|4|100|

Color Weight Height
red 12 160
green 4 100

You can also use HTML for tables .

Copy to clipboard

<table>
<tr>
<th>Color</th>
<th>Weight</th>
<th>Height</th>
</tr>
<tr>
<td>red</td>
<td>12</td>
<td>160</td>
</tr>
<tr>
<td>green</td>
<td>4</td>
<td>100</td>
</tr>
</table>

Color Weight Height
red 12 160
green 4 100

## Blockquotes

Blockquotes can be found in the editor bar button
Puting a greater than sign > in front of so a line will create blockquotes
Typing:

this is some blockquoted text
this is another line of blockquoted text

this is not blockquoted

this is another one
Results in:

this is some blockquoted text
this is another line of blockquoted text

this is not blockquoted

this is another one

This is not a native feature of Discourse, you can manually create a TOC by using HTML headings with the appropriate ID rather than the ## heading sytnax. Make sure your id is prefixed with heading-- , this is necessary because of the Discourse’s javascript app based architecture. Here is a quick example:

Copy to clipboard

- [link to first heading](#heading--first-header)
some text
more text
even more text
ok no more text


some text

more text

even more text

ok no more text

## Using LaTeX for Formatted Math

The is an official Discourse plugin that uses Mathjax to enable LaTeX based formatting. The LaTeX syntax is a beast on it’s own so I’ll only point out a few examples. Look at the quick reference guide on stack exchange for more information. The basic usage is to use $\some inline latex expression$ or to express in multi-line surround the LaTeX with $ . Copy to clipboard $
H(z)&=\sum_{k=0}^{\infty}{(k+1)z^{-k}}\\
&=\frac{z^2}{(z-1)^{2}}
\end{align}
\$


H(z)=∞∑k=0(k+1)z−k=z2(z−1)2

There is color text and a variety of symbols( αωγβΩΓ ), fonts availble( HELLOWORLD ), and other ways to express things (((((x)))))

## Using HTML

### Other

If you’d ever like to see how someone else created their post you can use the following URL format to view the raw markdown https://forum.example.com/raw/{topicid}/{postid} take a look at the current post as an example.

### Aligning items

If you’re trying to align images or wrap text, there isn’t a really great tools for either of these things. It’s possible with custom plugins, but it’s not yet supported in native Discourse.
