Simple Module in Craft CMS 3 How do I create a simple module for one website in Craft?. I don't have much experience in Craft CMS.  I have tried from 3 days but I cannot get an answer. I'm following all the tutorials that I can find, but none I feel are clear. Any recommendations on the simplest of examples, even if it's just outputting a variable.
Start with the manual: https://docs.craftcms.com/v3/extend/module-guide.html

This blog post covers module development in more detail:

It includes a link to generate a scaffold module, which should work out-of-the-box.
