How Do You Add Documents and Acrobat Reader To Your LG Rumor Touch?

I have an LG RT from Virgin Mobile and I has saw that you can post Note with NotePad and add Documents with... Well, Documents... Anyway, I tried to look up how to add Docs but I couldn't fine any :(. Then I saw that they said to add Docs you must have Acrobat Reader. I couldn't fine how to add that either! Can anyone give me a link or tell me how for, at least, Acrobat Reader.How Do You Add Documents and Acrobat Reader To Your LG Rumor Touch?
I have the sprint version and all i did was put a word document on my memory card and then i went to tools and clicked on the document viewer and the document just popped up. I don't think you need to have Acrobat Reader, because I did it without it.
