Help:Editing

To edit a page:

• Click on the Edit tab—it's usually near the top of a page, to the left of the search box. If you're on a discussion page and you want to start a new section, click Add topic. Or, if you just want to edit a single section, click the "[edit]" link to the right of the section heading.
• Make some changes in the edit box.
• Enter a brief summary to describe your changes.
• Click Save page.

You can use the toolbar above the edit box to insert special characters, emphasise text, embed files, create links, make section headings, lists, and tables, and control formatting in various other ways. The "Help" section of the toolbar provides more information on wiki markup.
