Part of an administrator's role is to delete pages due to speedy deletion criteria, XfD discussions, or articles that have been proposed for deletion.
Deleting a page is relatively easy. Basically, click on the "More" dropdown at the top of the page (the delete option will only appear if you are an administrator logged in to your account), enter a reason (or edit the automatically supplied reason), and hit delete. That's all there is to it. On very rare occasions, you might post a note at the Deletion Review page to allow others to review your speedy delete action, but that is not a usual practice. Restoring etiquette is the same as deleting etiquette when done per consensus such as per an XfD. However, if you restore a page without a consensus, it is considered proper to notify the page deleting admin of your actions and the reasons for your actions.
Below are instructions on how to delete and restore pages. Please follow the instructions to delete and then restore the page Wikipedia:Administrators' guide/Deleting/delete2. The instructions below also describe how to use the revision deletion function and restoring selected revisions. As a new administrator, you may not want to use the delete/restore revision extension until you have adequate experience with basic admin functions.
