<p>Welcome to $settings->sitename!</p>
|
|
<p>$settings->sitename is powered by Pepperminty wiki, a complete wiki in a box you can drop into your server.</p>
|
|
<h2>Navigating</h2>
|
|
<p>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).</p>
|
|
<p>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 $settings->sitename's administrator may have changed these settings to allow anonymous edits.</p>
|
|
<h2>Editing</h2>
|
|
<p>$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:</p>
