Here are the installation instructions for your new eBook. These are for Apple devices and Kindle only; the ePub files are universal and can work on various platforms, but that's beyond what we can cover.  We also cannot provide technical support, but it's a pretty straightforward process.

APPLE DEVICES

1. Double-click the ePub file. It will automatically open in Apple Books and get added to your library.

2. That's it! Start reading.

KINDLE

1. Go to this address (you need to be logged into your Amazon account): https://www.amazon.com/sendtokindle

2. Upload your file and you're done.
