Hello! Welcome to the Wikipedia Tutorial. Wikipedia is a collaboratively edited Internet encyclopedia to which you can contribute. This series of pages will give you the basic skills and knowledge you'll need to start helping us build this project.

Each page will discuss a useful feature of the wiki software, a piece of style and content guidance, information about the Wikipedia community, or important Wikipedia policies and conventions.

Keep in mind that this is a tutorial, not a definitive policy page or an extensive manual. If you want more details, throughout the tutorial there are wiki links to other Wikipedia pages. Those pages have more information on the topics here. You don't need to look at them now, but you can if you want. You might want to open them in a separate window (or a separate tab if your browser supports this feature), so as to stay on the tutorial.

There will also be links to spaces where you can practice what you're learning. Take advantage of the chance to try things out and play around. Nobody will get upset if you screw up an experiment in these practice areas, so play around and see what you can do.

Note: The location of links mentioned in the tutorial assume you are using the default page layout. If you are logged in as a registered user, and have changed your default preferences, they may be in other locations.

Ready? Then let's begin.
