I'm reading Daniel Sipos's Drupal 9 Module Development (though my Drupal install is actually version 10). Today I added a `.module` file that contained some help text for my "Been Here Before?" module. The help text used Drupal's built-in "help_hook". This new help message isn't a change that users can see on the public-facing site. But when I view the Help pages in the admin panel, I can see the help text I added to the module.
Here is the roadmap for where I plan on taking this module in the coming weeks:
PHP is a very flexible programming language that drives many of the Internet's most popular sites. Besides being the backend language for popular frameworks such as WordPress and Drupal, PHP is also used to perform maintenance and connectivity tasks on many web servers and other servers.
