Google Markup Helper Question!

Hey everyone!

I have a struggle with google markup helper in Software Applications section. Basically our company had developed a plugin to another software, so initial question - should I mark it as "Software Applications" or "Products" ?

Problem after is that the page (besides the main product description) has 6 different "parts" of this software (like different features of this program), each of them has own link and page (with their description).

Question is: how I can mark these descriptions as descriptions? I tried to use https://pending.schema.org/SoftwareApplication , but it seems I don't get where to look for the piece of code I need.

What I can do so far:

-Name (name of the program)
-Download URL
-I marked all another URL's by - URL
- Image (screenshot of the program)

I am not sure if this is enough, or I should go forward and mark all addons to this software with unique tags?

Looking forward for any help!

Schema markup is code (semantic vocabulary) that you put on your website to help the search engines return more informative results for users. If you’ve ever used rich snippets, you’ll understand exactly what schema markup is all about.
