A note about editing on mobile devices: Most Wikipedians prefer to edit from a computer, as the editing interface works better there. You can edit from a mobile device, though. See this page for more information.

VisualEditor is a What You See Is What You Get-style editor for Wikipedia. It's very simple to learn. It is an alternative to the Source editor, the primary editing interface which works more like a plain text file and allows you to directly edit the wiki markup text (wikitext). While VisualEditor is simpler to use, the Source editor can be more effective for some tasks.

This tutorial introduces the basics of using VisualEditor. Full instructions can be found in the VisualEditor user guide. You can enable VisualEditor through the Editing tab of Preferences: At subsection "Editor", make sure the checkbox "Enable the visual editor" is selected, and simply save your settings.

On talk pages, the VisualEditor is available when you use the 'Add a new topic' or 'Reply' buttons, but not when you click 'Edit' at the button at the top right.

After you've enabled VisualEditor, you can edit any page that uses it by clicking on the "Edit" tab at the top of the page. (A long page may take a few seconds to load.)

You can also open VisualEditor by clicking on the "edit" link on any section of an article. You can toggle between using VisualEditor and Source Editor whilst editing most pages.
