Start by adding new questions and answers to the FAQs menu on your dashboard.
Don’t forget to turn on the question after adding it, so it will be displayed on your website. If you do no longer want to display the question, or it is not necessary at the moment, you can turn it off.
Once you have written your question and answer, you can add it to a specific category (or add a new category). This way it will be easier for the customer to filter the questions.
