In the pop-culture folklore surrounding vampires, it all starts with a bite on the neck. In some cases that's just about all it takes, in others there is a complete exsanguination followed by a minute return flow that Awakens the fledgling from dead into Everlasting Life.
In real Vampirism, the process is a bit easier. It all starts with buying a book. The act of purchasing the text links you in to the Vampire Family. It sets up the proper initial condition needed to Contact the Gods.
The video below explains this in more detail. One thing I should also mention is that a gift copy will work as well. I gave my fiancée a "bite on the neck," and although it did take a while, she is now also an active member of the Temple of the Vampire and is enjoying both Dayside and Nightside success in her unending life. However, a stolen copy won't work. At least, you should pray to whatever Gods you believe in that a stolen copy won't work. If it does, then you will be face to Face with Someone who knows you've stolen a copy of the Vampire Bible. If such a being exists, then all you've done is invited an actual, real Vampire into your life and shown yourself to be His or Her enemy.
