Learn something new. Contribute what you know.

Wikimedia projects are made by volunteers. Like you.

Editors contribute new articles and improve current articles. Developers write and debug the code that makes the wikis go. Galleries, libraries, archives, and museums share their collections and expertise. All of us have knowledge to share. Here’s how to join our global community.

Get involved as a Wikipedia editor

No previous experience is needed to start editing Wikipedia. Visit the Teahouse for a friendly place to learn about editing. Veteran editors answer questions and help new editors become accustomed to Wikipedia culture.

Join an event or online community

Edit-a-thons and WikiProjects bring people with similar interests together to create and improve Wikipedia articles around a common theme. There are frequent workshops to train new editors.

Find your local Wikimedia community

There are over 170 active Wikimedia affiliates around the world. Each supports Wikimedia projects within a geographical region or thematic area. Find yours.

Contribute your coding skills
