ArduCAM ov2640 with Arduino Mega and bluetooth module HC-05

I am working on project where I want to integrate the ArduCAM 2640 camera with Arduino Mega R3 (without ArduCAM shield) which is connected to a Bluetooth transceiver module HC-05. I would like to get help on how to start with this integration and also would appreciate people to share their codes as I am a beginner and all your help and guidance would be appreciated.
