Wikipedia is the encyclopedia and is hosted by a non profit organisation called the Wikimedia Foundation (WMF). Participants to Wikipedia are called wikipedians.
The WMF host other projects, collectively called Wikimedia projects.Wikimedia projects include Wikipedia, Wikibooks, Wikisource, Wikimedia Commons, WikiVoyage etc.
We refer to wikimedia movement or wikimedia community when we talk about all the contributors to and participants of Wikimedia projects.
Members of the movement can organize themselves in to structured groups, called Chapters or UserGroup or ThematicGroup (see Wikimedia in Africa to read more about those organisations).
Every wikimedian can organize activities around Wikimedia projects if they wish so. It is not mandatory to be in an organization to do so (but often, that can help...).
There are several Africa-based Wikimedia groups and organisations across Africa and beyond, that run a host of projects that help to contribute information and images about Africa to Wikipedia and Wikimedia projects so that people on the continent can see their realities represented and people outside of Africa can see the many different peoples and cultures that make up the continent. This page list some of the activities organized by wikimedians that either happen across Africa or add content about African subjects to Wikimedia projects, specifically Wikipedia. Feel free to join in, or let them inspire yourself if you want to organize a new activity. If you want to find out about
