Review of what you've learned
When you think you're ready to publish (save) your changes, there are a few things to do first.
You should preview your changes to check that your edits look as you intended, by clicking the Show preview button. We all make mistakes, so this step can help you catch them before the article is changed.
Write a short edit summary in the "Edit summary" box to help other editors understand what change you have made and why you've made that change. It is okay for your explanation to be quite short. For example, if you are making a spelling correction, you might just put "fix typo".
If you've made a minor change that should be uncontroversial, such as a spelling or grammar correction, you can check the "☑ This is a minor edit" box. Minor edits are those that do not modify the meaning of a page or make a change that another editor might reasonably dispute.
To add a page to your Watchlist, so that you'll be notified of any further changes, use the "☑ Watch this page" box.
Previewed the page? Written an edit summary? Then you are ready for the final step: Click the Publish changes button, and your changes will instantly be uploaded to Wikipedia!
