Wikipedia:Training/core/Citing sources
This how to create citations manually on Wikipedia in order to cite appropriate sources.
Any editor can challenge unreferenced material by adding a {{fact}} tag which adds the famous [citation needed] tag. Editors are encouraged to remove unreferenced contentious material on sight. Wikipedia no longer accepts new articles on living people unless they are referenced, and other unsubstantiated articles often end up getting deleted. So when you add information to an article, be sure to include your references, preferably in the form of inline citations. Citations allow other editors and readers to verify the information.
To see an example of how the simple elements of <ref></ref>, ==References==, and {{reflist}}
are used to create an article, please bookmark this page then come back to the training.
