Thank you Ebook for helping me with the Joomla’s Component development.
I learned it easier than what is posted on the Joomla’s Documentation.

I had a hard time yesterday on working the given tutorial of Joomla to create a component. I did follow each step and tried copying and pasting the code. Still the code is not found after installation.
Fortunately, I got into a Plugin Tutorial for CB that did the work. I hope that I can search for a better tutorial other than the available at docs.joomla.org and bend Joomla.
