Help with pages

Hello, I know there are podcast on this subject, and I have watched them many times to try to understand this. But, I am confused. 1. I am using pages on my IPhone 5c. 2 Along with this, I ma using my Focus 40 Braille display. 3. I have pages installed on my phone. My confusion or just question is, I need help understand they layout of the telplements on the pages app. I need an explanation of how to get a document to a word doc so that it can be read and edited on my PC later. I know this might not makesense, but I tried to explain this the best way I could. Plus, how can I take a document I created on my computer and do some editing with it on my phone. Is there a app for that. I read the text editing post on here, but I guess I just need someone to give me some instructions while I have the app running. Thanks for listening to this. I hope someone can help.
