When editing an article on Wikipedia, you will see a small field labeled "Edit summary" shown under the main edit box. It looks like this:
Edit summary (Briefly describe your changes)
Please be sure to provide a summary of every edit you make, even if you write only the briefest of summaries. The summaries are very helpful to people browsing an article's history.
Edit summary content is visible in:
Please use the edit summary to explain your reasoning for the edit, or a summary of what the edit changes. You can give yourself a reminder to add an edit summary by setting Preferences → Editing → Prompt me when entering a blank edit summary. Thanks! Andrzejbanas (talk) 19:09, 16 October 2017 (UTC)
This is the discussion page for an IP user, identified by the user's IP address. Many IP addresses change periodically, and are often shared by several users. If you are an IP user, you may create an account or log in to avoid future confusion with other IP users. Registering also hides your IP address.
