In this chapter, we cloned the HTML content module into the
Hello World module. The
Hello World module was created, installed, configured, and uninstalled. After configuration, we inserted some data and showed it at the frontend.
You found out how code works in the
Hello World module and saw its file and folder structure. We described the code that we used in the
Hello World module's files. By referring to the
Hello World module, you should be able to go through other modules and become familiar with them. Now, we need to go deeper into the module, so in the next chapter we will describe the code for extensions. You will learn about the global library methods of OpenCart and how to create a shipping extension.
