$settings->sitename Help

Welcome to $settings->sitename!

$settings->sitename is powered by Pepperminty wiki, a complete wiki in a box you can drop into your server.

Navigating

All the navigation links can be found in the top right corner, along with a box in which you can type a page name and hit enter to be taken to that page (if your site administrator has enabled it).

In order to edit pages on $settings->sitename, you probably need to be logged in. If you do not already have an account you will need to ask $settings->sitename's administrator for an account since there is not registration form. Note that the $settings->sitename's administrator may have changed these settings to allow anonymous edits.

Editing

$settings->sitename's editor uses a modified version of slimdown, a flavour of markdown that is implementated using regular expressions. See the credits page for more information and links to the original source for this. A quick reference can be found below:

Type This	To get this
`_italics_`	italics
`bold`	bold
`~~Strikethrough~~`	~~Strikethough~~
`code`	`code`
`# Heading`	Heading
`## Sub Heading`	Sub Heading
`[[Internal Link]]`	Internal Link
`[[Display Text\|Internal Link]]`	Display Text
`[Display text](//google.com/)`	Display Text
`> Blockquote > Some text`	Blockquote Some text
`- Apples * Oranges`	Apples Oranges
`1. This is 2. an ordered list`	This is an ordered list
`---`
`![Alt text](//starbeamrainbowlabs.com/favicon-small.png)`

In addition, the following extra syntax is supported for images:

Size the image to at most 250 pixels wide:
![Alt text](//starbeamrainbowlabs.com/favicon-small.png 250px)

Size the image to at most 120px wide and have it float at the right ahnd size of the page:
![Alt text](//starbeamrainbowlabs.com/favicon-small.png 120px right)

Administrator Actions

By default, the delete and move actions are shown on the nav bar. These can be used by administrators to delete or move pages.

The other thing admininistrators can do is update the wiki (provided they know the site's secret). This page can be found here: Update $settings->sitename.
