Writing Instructions For Yourself
Many pages in this book contains step-by-step instructions. These setup instructions can be complicated, so make sure to securely write and store instructions for yourself.
Make sure that you can access these documents whenever you are handling funds.
This book generally recommends the use of Tails OS and the KeePassX password database in securing important information, such as instructions for yourself.
I would recommend writing your instructions down on Offline Tails (a computer that has the Tails OS installed but is disconnected from the Internet), then storing them encrypted in a KeePassX database or an encrypted 7z archive.
Don't worry if you don't know how to use Tails OS or KeePassX right now. We'll talk about how to use them later on in the book.
