Today you are going to get your website setup and Wordpress installed on your server. You will build your self-hosted website architecture, and understand what you are doing along the way. At the end of today users will be able to type your domain name into their browser and see an 'Under Construction' message.
Today you will be adding a theme to your website and getting your pages set up. You will be adding your colour scheme to the website, along with your logo and any image and text content. By the end of the day you will have a working contact form and a homepage that describes your business.
These are lessons which you may need during your build, but you may not need them at all. The course lessons will link you to these lessons at the point where you would need to use them, otherwise you won't need these.
