4) Go to “Design” –> “Widget’ –> Drag the widget name “Random Posts Widget” and put into sidebar(Put anywhere you like).
5) Do a little bit setting by click the “Edit” on the Sidebar Widget.
6) Done !!

It’s fast, easy and clean to use. Normally this plugin can help you to encourage your reader to read your older post. If they found that your older posts are interesting, they will keep searching and read your posts. Try it out and have fun ^^
