How did Carlyle Cullen become a vampire?

He was out searching for a vampire when a monster came out of no where and it bit him. so Carlisle crawled into a potatoe storage and waited for the venom to spread............. this twihard says, "read the book; Edward explains everything in Twilight pages 331-341 if you want the whole story, 331-332 if you just want the transformation. look it up yourself next time."
