I was issued this problem to work on and got stuck trying to clear the page and load a blank screen with text, what step do I take?

the problem at hand:

1. Create a new Mage module with namespace “Bsi” and Module Name “Final”.

   a. Measure of success: The homepage loads without error.

   Note: All the following steps should be done inside the new module.

2. Create a controller TrainingController with action CustomerAction

   a. The response payload should be plain text “Hello World”.

   b. Measure of Success: You can stop the debugger in your controller action, and you see the text “Hello World” when accessing the URL.

MagentoSampleappcodelocalBsiFinaletcconfig.xml looks like this:

Most of the results I have been able to find just seem to expect it to be common knowledge so any help would be really appreciated and there is nothing that i can be expected to know that wouldn’t be helpful to relay!
