To edit a document in word, you will need a word application installed in your computer or device. You will also have an existing document which you can add or remove items from.
Page layout is a term that is used to describe all commands that help you position your document for printing. Setting up your document in Microsoft Word entails putting in place the pages, margins, and orientation of the document. How you effectively set these items up will affect the final look of your document when it is printed.
