The simple answer would be that you add your module to a mojoPortal page just like you do any other module/feature. You would edit a page and select your module from the list of available features. I assume your issue is bigger than administration of the pages though.

Know that you are starting out with module development, and with the details that you have provided, the issue could be any number of places. If we narrow it done we might be able to help. Couple of things to check...

1. In the root of mojoPortal does the directory containing your module's files exist?
2. When you go to Admin > Advanced Tools > Feature Installation and Configuration does your module exist in the list?

If the answer to step 2 is yes, then you should be able to add it to mojoPortal pages.

Let's start with these questions and then we will try to narrow the issue down.

When you say:

I followed your documentation

Which specific documentation are you referring to?

As I mentioned in my last post the problem could be a number of things, but without going through a whole bunch of back and forth of questions and answers and potential of trial and error there is no easy way to pin point it. I am going to post a few links that really helped me when I was starting out. Even if you have done some of these before, I suggest just starting a new custom module. By doing that you may quickly figure out what you are missing.

I would recommend reviewing the Hello World walk through.

Also, if you have not yet watched the Video Tutorial series, that is highly recommended and would probably answer a lot of your questions.

I also found this tutorial very helpful when I was starting out.

Good luck and hope this is helpful.
