Summary
Review of what you've learned

Once you're happy with your changes, it's time to save them. When you save your edits, they immediately change the Wikipedia page you were editing. (To cancel your edits, just close your browser window.)
When you're done editing, click the blue Template:Menu icon blue button in the toolbar This will open a dialog box where you should summarise your edits. This summary helps other editors understand what you've changed.

You can mark your editing as minor if you just made uncontroversial spelling or formatting changes. Also, if you want to be notified of further changes to the page, you can and add it to your Watchlist.
The "Review your changes" button shows you the Wiki markup source code for the changes you've made, if you want to check. The "Resume editing" button returns you to the page you were editing, where you can make more changes (you can save all of your edits later).
