I guess this is the section I asked you to add to explain what render items are.   It still seems confusing to me; I wouldn't understand it if I didn't already know what a render item is.

I'd add an example.  How about this?

Store item:
```
{
    lastName: "Smith"
    firstName: "John",
    department: "marketing"
}
```

Render item:

```
{
    name: "John Smith"
    departmentIconClass: "marketingCls"
}
```

Hopefully you can come up with something better but that's the general idea I was looking for.
