You can edit Wikipedia by clicking the Edit button on any article, making your changes in plain text, and saving them with a brief note about what you changed
Wikipedia is not locked down the way most websites are. Nearly every article has an Edit button (or Edit source button) that takes you to a text box where you can add information, fix errors, or rewrite entire sections. Your changes go live immediately on most articles, though some pages require approval from experienced editors before your work appears.
The barrier to editing is low by design — you do not need permission, do not need an account, and do not need to know code. What you do need is to follow Wikipedia's core rules: cite where your information comes from, do not insert your own opinions, and assume other editors are acting in good faith even when you disagree with them.
Key Takeaways
- Click the Edit or Edit source button at the top of any Wikipedia article to open the text editor where you can make changes.
- All edits require a source — a book, news article, government document, or other published material you can point to — or your change will be removed.
- Write a one-sentence note in the Edit summary box before saving, explaining what you changed and why, so other editors understand your reasoning.
- Creating an account takes 30 seconds and gives you a user page, lets you watch articles for changes, and makes other editors more likely to trust your work.
- Some articles are protected and require you to have an account or a certain amount of editing history before your changes go live.
Finding and opening the edit box
At the top of every Wikipedia article, near the title, you will see a row of tabs. One of them says Edit or Edit source. Click it. The page will reload and show you the article text in an editable box — this is where you make your changes.
On some articles you will see an Edit button next to individual section headings instead. Clicking that button opens only that section for editing, which is faster if you are changing just one part of the article. Both routes lead to the same text editor.
If you do not see an Edit button at all, the article is protected. This usually means it covers a controversial topic or gets vandalized often. Protected articles require you to have an account and sometimes a minimum amount of editing history before you can make changes. The protection notice will tell you what is required.
Making your changes in the text editor
The edit box shows the article in plain text with some basic formatting codes. You can add text anywhere by clicking where you want it and typing. To delete text, select it and press Delete or Backspace. To change something, select the words and type over them.
Wikipedia uses simple formatting: text between two single quotes becomes italic, text between four single quotes becomes bold, and headings start with equals signs (== Heading ==). You do not need to memorize these. For most edits — fixing typos, adding a sentence, correcting a date — you just type normally and save.
If you are adding a fact that is not already in the article, you must add a citation. At the end of your new sentence, type <ref></ref> and put your source information inside the tags. For example: <ref>Smith, John. "Article Title." Publication Name, 2020.</ref> Wikipedia has templates that format citations automatically, but a basic one works fine for your first edits.
Writing an edit summary and saving
Before you click Save, look for the Edit summary box — a small text field below the main editor. Write one sentence explaining what you changed. Examples: "Fixed spelling of mayor's name" or "Added citation for population figure" or "Removed unsourced claim about founding date." This note helps other editors understand your reasoning and makes them more likely to keep your changes.
Click the Publish changes button (or Save page on older versions of Wikipedia). Your edit goes live immediately on most articles. If the article is protected or if you are editing without an account, your change may go into a queue for review. You will see a message telling you what happened.
Understanding Wikipedia's core rules
Wikipedia has three rules that matter most: cite your sources, do not add your own opinions, and assume good faith. If you follow these, your edits will survive and you will not run into conflict with other editors.
Citing sources means pointing to a published book, news article, academic paper, government document, or other material that supports what you wrote. Wikipedia does not accept "I read this somewhere" or "this is common knowledge." If another editor removes your change and says "citation needed," they are asking you to prove it came from somewhere real. Add the source and they will usually restore it.
Do not add your own analysis, opinions, or original research. Wikipedia is an encyclopedia, not a blog or opinion platform. If you think a fact is wrong, find a published source that contradicts it, then cite that source in your edit. If you cannot find a source, you cannot add it.
Assume good faith means: when another editor removes or changes your work, assume they had a reason related to Wikipedia's rules, not that they are trying to hurt you. Read their edit summary, look at the rules, and respond calmly. Most disagreements get resolved through discussion on the article's Talk page (a tab next to Edit at the top of the article).
Creating an account versus editing without one
You can edit Wikipedia without creating an account. Your edits will be attributed to your IP address instead of a username. This works fine for small fixes and corrections.
Creating an account takes 30 seconds and gives you real advantages. You get a user page where you can introduce yourself, you can watch articles and get notified when they change, and other editors are more likely to trust your work because they can see your editing history. Some articles require an account before you can edit them at all. If you plan to edit more than once, create an account.
To create an account, click the Log in or create account link at the top right of any Wikipedia page. Choose a username, enter an email address, and set a password. You do not need to verify your email to start editing, though doing so unlocks a few extra features.
What happens when your edit is challenged
If another editor removes your change or adds a tag saying "citation needed," do not take it personally. This is how Wikipedia works. Read their edit summary to understand why they acted. If they removed it because it lacked a source, find a source and add it back with the citation. If they disagreed with your wording, look at the Talk page to see if there is a discussion about it.
The Talk page is where editors discuss changes to an article. Click the Talk tab at the top of the article to see conversations about what should and should not be included. If your edit was removed, you can leave a message there explaining your reasoning and asking why it was taken out. Most editors will respond and explain their thinking.
If you and another editor keep reverting each other's changes (removing and re-adding the same edit), stop and use the Talk page instead. Wikipedia has rules against edit wars, and continuing to revert will get you blocked from editing. The Talk page is the way to resolve disagreement.
Common mistakes that get edits removed
The most common reason edits are removed is lack of a source. If you add a fact and do not cite it, another editor will remove it or tag it as needing a citation. Before you save, ask yourself: could I point to a published source for this? If not, do not add it.
The second most common mistake is adding promotional language or opinions. Wikipedia articles should be neutral in tone. Do not write "the brilliant scientist" or "the company's innovative product." Write "the scientist" or "the product." Let the facts speak for themselves.
The third mistake is editing articles about yourself, your business, or your family. Wikipedia has strict rules about this because of conflicts of interest. If you have a personal stake in the article, disclose it on the Talk page and let other editors make the changes. If you edit without disclosing, your work will be removed and you may be blocked.
Frequently Asked Questions
Do I need to be logged in to edit Wikipedia?
No. You can edit without an account, and your changes will be attributed to your IP address. However, some articles require you to have an account, and creating one takes 30 seconds and gives you advantages like the ability to watch articles for changes.
What if I make a mistake in my edit?
You can fix it immediately by clicking Edit again and correcting the text. If another editor notices the mistake first, they may fix it for you. Either way, mistakes are normal and not a problem — Wikipedia is designed to be edited and improved over time.
How do I know if my source is good enough?
Wikipedia accepts published books, news articles from established outlets, academic papers, and government documents. It does not accept blogs, social media, or websites that anyone can edit. If you are unsure, mention your source on the Talk page and ask other editors whether it is acceptable.
Can I edit Wikipedia on my phone?
Yes. The mobile version of Wikipedia has an Edit button just like the desktop version. The text editor works the same way. Some people find it easier to make small fixes on mobile and save longer edits for a computer, but both work.
What if someone reverts my edit?
Click the Talk tab at the top of the article and leave a message asking why your edit was removed. Include your reasoning and cite your source. Most editors will respond and explain their thinking. If you disagree, discuss it on the Talk page rather than re-adding the edit yourself.
