Your User (Senior's) Pages
1) The default area is your User's area, their Category Pages (all things specific to the app are Capitalized), and Item Pages within a Category.  Either a Page is a Category Page or Item Page.  For now, no mixing.
2) After exploring the default Pages, you'll be ready to edit :-)
Editing Your User Pages
1) Adding an Item
    a) Go to an Item Page (you'll know because anything you select on that Page actually *does* something, versus showing you more stuff).
    b) Tap the Login button on bottom left.
    c) Enter "Shared" (the use of " " and <> always means to type what is *within* the quotes/brackets, NOT the quotes/brackets! :-)  **Note: To Log In, you simply type of the name of that User.  Eventually, you'll create a new User, and to Log In to him/her, you'll just his/her name.**
    d) Now you are Logged In and can do things that your User cannot.
    e) Tap the pencil in upper left (a lot of this is explained within the app when you do something).
    f) Now you are in Editing mode. You'll notice the wavy lines around the pencil. To exit Editing mode, just tap the pencil again.
    g) Tap any Slot (an area on a Page that has a Category, Item, or is blank/has an X within).  When you are *not* in Editing mode, the blank Slots have a red X for your User to know that those don't do anything.
    h) Choose Add Item.
    i) You'll next select a Picture to represent that Item.  An Item is a Picture to represent it, and the Action that happens afterward, such as showing the picture larger with music, playing back an old time radio show, or playing a video.
    j) You can choose to use one of the Shared Pictures, or Take/Import your own.
    k) Next, you'll be asked if you want some Audio or Video to happen.
    l) If you do, you can choose to select, once again, from my Shared Library, or bring in your own.
    m) That's it. You should now have a new Item within that Item Page.  Just tap the pencil again to exit Editing mode and you should be able to activate that Item!
2) Adding a Category
    a) Just like above, except after selecting a Picture, you won't have an option for an Action, because the Action is simply opening that Category page, which will be blank at first.
3) If you make a new Category Page, it will start as blank, of course.  You can select for it to be a Category Page or Item Page by just choosing what you want for its first Slot.  Conversely, should you want to convert one Page type to the other, simply Delete everything on that Page and start over.
4) That's it for Editing Pages! :-)
Now on to the 'tougher' stuff:
Managing (editing, creating, deleting) your Media
1) While Logged In, tap the Media icon in upper left.
2) Name your iPad (red, bottom right). Use the Apple ID of that iPad, or some email that you know is yours.  No actual 'talking' to Apple to confirm the ID occurs.  It's just a good idea ;-)
3) The app checks to make sure that email address is available or that you have used it before.
4) Now, not only are you logged in, but our server (a data storage area accessible to my app; some call it a 'cloud' or 'the cloud) will know who you are, and have a devoted folder for any iPad that uses the same email address (name). With each new release of the app, you will *not* delete your current app unless instructed to.  That way, your iPad's name will persist :-)
5) There are 3 types of Media: Pictures, Audio, Video.  Simple!
6) They each work almost exactly the same way.  Go to each and examine the menus and you can confirm this.  Learn one, and you've learned, almost, all three! :-)
7) Things are pretty self-explanatory here. I try to be as 'instructional' as possible with my dialog boxes.  *Note* Once you're into the list of the Media, to get 'back' to the Media Management screen, tap the top heading/button that has the 2 horizontal arrows pointing to it.*
8) You should be able to just tap around, and Cancel or try things, without something 'breaking'.  Remember, this 'back end' (as it's called in programming lingo), is for the Contributor(s), NOT your User, EVER!  You are creating and managing your Media Libraries.  Back at the Pages area is where you select these Media for Categories and Items.  *Make sure you understand the difference between 'front end' (your User Interface (UI), that is, what your User sees), and the 'back end' for setting things up.  Yes, the Editing Mode of the front end IS for *you*, NOT your User, and it might be considered a 'middle' ;-)
In most cases, the next 2 sections will be necessary as your User's iPad will not be with you. But in some cases, when you are editing their iPad yourself, then you'll not need to Upload or Sync.
Uploading
1) Once you have Edited Pages and Media on *your* iPad, you'll want to Upload all the changes to your area on our server.  You've already claimed an area there #2 right above).
2) At the Media Management screen (it will have Shared Media Management at the top), simply tap Upload and away all your changes go! Couldn't be easier.
Syncing
1) Make sure they are Logged in as the same User as you were when you made your changes.
2) Make sure that someone *names* your User's iPad the same as yours.  Remember that Logging In is *not* the same as "naming the iPad."  Logging in gets you into the middle and back ends (#8 above) while naming your iPad(s) gets you (and 'them') into your area on our server.
3) For now, we're just playing around with the User named Shared to avoid confusion (although, everything is exactly the same once you start to Add Users).  These Shared Pages are those Pages that everyone that has access to the iPad(s) to.
4) Tap the Media icon from a User's Page, to get to Media Management.
5) Tap Sync and everything that was uploaded, should download to that iPad. Nothing at all should need to be done to get that User's iPad identical to yours.
Auto-Syncing
1) On the Media Management screen, you'll see Set Auto-Sync (bottom right, red). This tells the iPads connected with the name (email) you used to check with the server each night and automatically perform a Sync at your User's iPad.
2) On the Select a User Page, I will highlight those User's that have been updated.
3) On the Home Page (Audio, Cars, etc.) will be a new Category called New Stuff which will show just the new Items.  2 & 3 happen automatically with *any* Sync, manual or auto.
Beta Testing
1) First, good beta testers don't need 'hand-holding'. They know the drill and that they are expected to *think* things through. Basic questions should be answered by Google research or asking each other. This would include things about connecting to the net, deleting apps, etc.
2) Reporting bugs/glitches (the latter are just minor instances of the former) involves guiding me to reproducing the error(s) on MY iPad.  That means I need *specific* step by step instructions on how you produced the error.  General phrases like "It didn't work" don't help *anyone* ;-) If you're not specific, and you continue that way, I will have to drop you from the group.  That may sound harsh, but I've been working on this for 1 1/2 years; I want to finish it ;-)
3) In the event of a 'crash', when the app exits back to a Home screen, those are the most important bugs, and once again, try to reproduce it, step by step, keeping track of your steps.  Most times, you cannot. But sometimes you can find a pattern.
4) In the event I can't reproduce it here, I will need for you to send me your iPad's crash report.  No need to go into that here as it's a bit complicated (not "hard", though ;-) .
5) Another great way to document what went wrong is with a "screen shot." Simply press/hold your power button and tap the Home button.  Then a picture of that screen, with the error, will be in your Camera Roll and you can email it to me.
