Preview

It's a good idea to use the 'Show preview' button to see what your change will look like, before you save it. This is also related to tracking changes because every time you save, this is displayed to others as a separate change. This isn't something to worry about too much, but it's good to get into the habit of eliminating mistakes in your own work, by using a preview before saving, rather than saving several minor corrections afterwards.

How to link

By default, when you write a link (URL) as is, it will be transformed to an external link.

Images

Before you place an image on a page, you must upload the file. "Upload file" is usually an option in the Toolbox in the right sidebar.

You may use the "Embedded image" button at the top of the edit box to place an image, or other file such as sound or video.

If you want to include an image, the wiki formatting is: <code>[[Image:{name}|{options}]]</code> Where options can be zero or more of the following, separated by pipes:

• <code>thumb</code>, <code>thumbnail</code>, <code>frame</code>, or <code>frameless</code>: Controls how the image is formatted
• <code>left</code>, <code>right</code>, <code>center</code>, <code>none</code>: Controls the alignment of the image on the page
• <code>baseline</code>, <code>sub</code>, <code>super</code>, <code>top</code>, <code>text-top</code>, <code>middle</code>, <code>bottom</code>, <code>text-bottom</code>: Controls the vertical alignment of the image on the page
• <code>{width}px</code>: Resizes the image to the given width in pixels
• Special cases:
  • <code>page=1</code>: Displays the specified page when showing a djvu file
• <code>link={destination}</code>: Allows to link to an arbitrary title, URL or just nowhere (1.14+)
• <code>alt={alternative text}</code>: For changing the alternative text (<code>alt=""</code>) of an image (1.14+)

The options can be given in any order. If a given option does not match any of the other possibilities, it is assumed to be the caption text. Caption text can contain wiki links or other formatting.

Tables

Tables may be authored in wiki pages using either HTML table elements directly, or using wikicode formatting to define the table. HTML table elements and their use are well described on various web pages and will not be discussed here. The benefit of wikicode is that the table is constructed of character symbols which tend to make it easier to perceive the table structure in the article editing view compared to HTML table elements.

As a general rule, it is best to avoid using a table unless you need one. Table markup often complicates page editing.
