The Markdown plugin allows you to format text using a paragraph oriented subset of markdown. We add link syntax from Federated Wiki and task lists from GitHub.
See GitHub 
for plugin source.
# Features
This page offers an overview of those markdown features we support, and pointers to those plugins that provide support for those parts we choose not to.
# Paragraphs, Headers, and Blockquotes
A paragraph is simply one or more consecutive lines of text, separated by one or more blank lines. The markdown plugin will create a new page item when the enter key is pressed twice.
Headings are created by putting a `# ` at the beginning of the line. While ordinarily the number of `#`s indicates the header level, in Federated Wiki all headers within a page are considered to be `<h3>`.
Blockquotes are indicated using angle brackets, `> `, at the start of the line.
# Links
Write [ [ Page Titles ] ] inside of double square brackets to make an internal link to a new wiki page.
Write [ http://example.com/webpage.html webpage ] inside single square brackets to make an external link to another web page. Include a second field that specifies how the link is to appear in the rendered text.
By convention external links are represented by single lower-case words that identify what kind of page one will find when clicking the link.
# Images
The image plugin should be used for images.
# Code
In regular paragraphs, you can create code span by wrapping text in backtick quotes. However, entire blocks of code are better handled by using the code plugin.
# Emphasis
Markdown treats asterisks and underscores as indicators of emphasis. Text wrapped with one \* or \_ will be wrapped with an HTML `<em>` tag, typically shown in *italics*; while double \*'s or \_'s will be wrapped with HTML `<strong>`, typically shown in **bold**.
It is possible to prevent \* or \_ from being used to indicate emphasis by preceding it with a backslash `\*` or `\_`.
# Lists
Both of the standard HTML lists are supported, together with task lists from GitHub flavoured markdown. We render list markers in the left margin of the wiki page.
* Unordered, bullet, lists use asterisks, pluses or hyphens as list markers.
1. Numbered lists use a number, followed by periods, as list markers. _**N.B.** The numbering is reset for each markdown item._
* [x] Task lists are lists with items marked as either `* [ ]` or `* [x]` (incomplete or complete). A single click on the checkbox will edit the item and save the change like any other edit.
