This document provides an introduction to HTML (Hypertext Markup Language) and how it is used to create websites. It explains that HTML uses tags to tell a computer where text and images should go on a page and how it should look. Some common tags are described like <head>, <body>, and <footer> which define the different parts of a web page. It also provides a basic example of what HTML code for a simple webpage might look like. The document encourages highlighting HTML tags in a provided worksheet to practice identifying them.
