After developing your content, you should start to build a site map. This is a tree-like structure that outlines each page, along with sub-pages, or the major content on each page. Below is an example of a site map I might make for a personal website.
You are required to have at least the following sections within your final site. These could be as individual pages, or could be joined together with other content if appropriate.
You will of course have other pages/sections. These will be dictated by the main purpose of your content/site, and how this content needs to be presented.
