      Currently Pepperminty Wiki (the software that $settings->sitename uses) only supports the uploading of images, although more file types should be supported in the future (open an issue on GitHub if you are interested in support for more file types).

      Uploading a file is actually quite simple. Click the "Upload" option in the "More..." menu to go to the upload page. The upload page will tell you what types of file $settings->sitename allows, and the maximum supported filesize for files that you upload (this is usually set by the web server that the wiki is running on).

      Use the file chooser to select the file that you want to upload, and then decide on a name for it. Note that the name that you choose should not include the file extension, as this will be determined automatically. Enter a description that will appear on the file's page, and then click upload.

      $settings->sitename's editor uses an extended version of Parsedown to render pages, which is a fantastic open source Github flavoured markdown parser. You can find a quick reference guide on Github flavoured markdown here by adam-p, or if you prefer a book Mastering Markdown by KB is a good read, and free too!

      Tips

      • Put 2 spaces at the end of a line to add a soft line break. Leave a blank line to add a head line break (i.e. a new paragraph).
      • You can add an id to a header that you can link to. Put it in curly braces after the heading name like this: # Heading Name {#HeadingId}. Then you can link to like like this: [[Page name#HeadingId}]]. You can also link to a heading id on the current page by omitting the page name: [[#HeadingId]].

      Extra Syntax

      $settings->sitename's editor also supports some extra custom syntax, some of which is inspired by Mediawiki.
      Type thisTo get thisComments
      [[Internal link]]Internal LinkAn internal link.
      [[Display Text|Internal link]]Display TextAn internal link with some display text.
      ![Alt text](http://example.com/path/to/image.png | 256x256 | right)Alt textAn image floating to the right of the page that fits inside a 256px x 256px box, preserving aspect ratio.
      ![Alt text](http://example.com/path/to/image.png | 256x256 | caption)
      Alt text
      Alt text
      An image with a caption that fits inside a 256px x 256px box, preserving aspect ratio. The caption is taken from the alt text.
      ![Alt text](Files/Cheese.png)Alt textAn example of the short url syntax for images. Simply enter the page name of an image (or video / audio file), and Pepperminty Wiki will sort out the url for you.

      Note that the all image image syntax above can be mixed and matched to your liking. The caption option in particular must come last or next to last.

      Templating

      $settings->sitename also supports including one page in another page as a template. The syntax is very similar to that of Mediawiki. For example, {{Announcement banner}} will include the contents of the \"Announcement banner\" page, assuming it exists.

      You can also use variables. Again, the syntax here is very similar to that of Mediawiki - they can be referenced in the included page by surrrounding the variable name in triple curly braces (e.g. {{{Announcement text}}}), and set when including a page with the bar syntax (e.g. {{Announcement banner | importance = high | text = Maintenance has been planned for tonight.}}). Currently the only restriction in templates and variables is that you may not include a closing curly brace (}) in the page name, variable name, or value.

      Special Variables

      $settings->sitename also supports a number of special built-in variables. Their syntax and function are described below:

      Type thisTo get this
      {{{@}}}Lists all variables and their values in a table.
      {{{#}}}Shows a 'stack trace', outlining all the parent includes of the current page being parsed.
      {{{~}}}Outputs the requested page's name.
      {{{*}}}Outputs a comma separated list of all the subpages of the current page.
      {{{+}}}Shows a gallery containing all the files that are sub pages of the current page.
