If you have any social account connected to your Amazon account, then during the kindle paperwhite setup process, you will be asked if you want to connect any of those accounts to your Kindle. You can also set parental control or continue to choose both the options later.
Now, you are all set for purchasing the books and other content from your Amazon Kindle account and delivering all that content to your Kindle Paperwhite wirelessly. If you have already purchased the content and are waiting for your Kindle paperwhite device to arrive, you can see all the content on the home screen of your Kindle paperwhite once you have connected it to the Wi-Fi and complete the registration.
Once the Kindle registration process is completed, a short tutorial will begin to clear your basics for using the Kindle paperwhite. Once the tutorial is finished, you will be able to see the home screen with a welcome note and a Kindle user guide. On the Home screen, you can also see the two built-in dictionaries i.e. Oxford Dictionary of English, and Oxford American Dictionary. Here, you can also see the content you have purchased.
So, these are some simple guidelines that can help you in setting up Kindle paperwhite. Follow the mentioned steps carefully and complete the setup without any hassle. Although, if you still have a doubt or you find the aforementioned guidelines difficult to execute, you can always contact the Kindle export and take their advice to get this done.
