First thing you need to do is install and activate the Quick and Easy FAQs plugin. Upon installation, the plugin will add a new FAQs section in your WordPress admin menu. You will need to visit FAQs > Add New to add your first frequently asked question. The FAQ editor looks very much like post editor. Add the question in the title field and answer in the post edit area. On your right hand column, you will notice the FAQ Groups box. These groups are like categories in WordPress posts. You can use groups to sort questions into topics or sections. Once you are done, click on the publish button, and repeat the process for all other frequently asked questions you want to add. After you have a few FAQs, it is time to display them on your website.
