Hello. Thank you for your contributions to Wikipedia.
When editing Wikipedia, there is a field labeled "Edit summary" below 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.
