I would like to alter an article on Wikipedia how do I do so?
All you have to do is click the Edit button at the top of an article's page. In the page that you see afterward, you can make your changes and then save them.
You won't be able to edit some Wikipedia articles, however - instead of an Edit button, such protected articles will show a View Source button.
Also, when editing an article, it is recommended that you click
Preview before you save your changes. This way, you can make sure that your changes were made as you intended.
For editing, you don't even have to log in. However, if you don't log in, there are a few disadvantages:
- Your IP address is posted and visible to the whole world - can lead to security issues
- You may lose some credibility
One last thing - it may be hard to get used to how formatting works on Wikipedia. That's why they wrote a cheatsheet for editors.
Just go to the relevant article, then click on "Edit" near the top right, make the changes you want, add a summary and click Save Page. The Cheatsheet could well be of use when you're doing this.
