    $settings->sitename Help

    -

    Welcome to $settings->sitename!

      $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:

      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.

          $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:

          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.

          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:
