Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
You can "name" the kindle anything you like. By default, if it is your first/only kindle, it will be named automatically on your account and assigned by amazon as something like Lynn's paperwhite, or Lynn's fire, depending on the model.
After you charge it, you need to connect it to your home wifi network, and after that you may be prompted to sign in or register it to your amazon account, and can then start buying books, apps, etc.
Do you need more help with this, Lynn?
What is it that you don't understand?I'm trying to help, but I need to know where you are getting stuck.
