Understanding WordPress is relatively easy once you get the hang of it. However, it can seem as overwhelming as learning a foreign language. If you are quite tech-savvy, you may find it easy to follow along with online tutorials to learn what you need to do to set up your website, choose a theme and post content. Another option is to take a class with someone who can walk you through the steps to achieve what you want to achieve. Alternatively, you can pay someone to set up your website and then ask them to show you how to make updates.
