Wikipedia is a free encyclopedia that anyone can edit. But there’s a catch – you have to have some experience editing Wikipedia pages. If you see a page that needs improvement, you can click on “Edit this page” on the bottom right and then type in your changes. Once you’re done, you can click on the “Save page”. If it’s OK, you can “Save your changes” and your edit will be visible to other people. For a newbie, we recommend a mentor who is a professional Wikipedia writer.
