500 million people use it. Every. Single. Month.

All those legitimate news articles you see on social media? Use them to cite facts in Wikipedia! Just click edit, write your fact, then press ‘cite’ to reference your fact. Add the link, press save and you’re done. Wikipedia is a secondary knowledge source, that means it needs citations from reliable sources to back up its claims. Don’t be deterred if your edits ever get changed by someone. Keep in mind that editing is a 2-way street and the number one goal of Wikipedia is to create articles with a neutral point of view.

Upload your photos - if you took a photo then you own it and you can upload it. Go to commons.wikimedia.org, press upload and follow instructions from there.

After your photo is on commons, go to the Wikipedia page you want to see it in, press edit, then press ‘insert’ and click ‘media’. Type in the name of the photo and add it to the article.

You can also share videos and photos on YouTube, Vimeo, Flickr and other sites - just mark them CC-by and let people know they are there. Others who are more technically savvy can migrate it. Just make a note on the ‘talk’ page of any Wikipedia article with a link to your photo or video. Marking it CC-by makes it legal to move anywhere. IMPORTANT! No not mark it cc-by-nc or cc-by-nc-nd because those non-derivative, non-commercial use licenses are incompatible with Wikipedia.
