How to create your first dupal Module

Now i explain the simple and easy steps to create a first drupal module. Our first module will show simple text, format it, and display it as a block in the site’s layout. There are two important files that every module must have.

The first is .info file, and the second file is .module (dot-module) file, which is a PHP script file.
