-Whichever of the compatible cameras you are using the sketch will include libraries and definitions for them all, meaning no modification to the sketch is necessary to get it working. The sketch will capture frames into the framebuffer and then print a live camera feed to the display.
+Whichever of the compatible cameras you are using the sketch will include libraries and definitions for them all, meaning only one line needs to be changed depending on what camera you will be using. The line that needs to be changed is this one:
+
+```arduino
+#define ARDUCAM_CAMERA_HM01B0
+```
+
+Depending on what camera you are using it should be changed accordingly:
+
+- HM01B0: `#define ARDUCAM_CAMERA_HM01B0`
+- HM0360: `#define ARDUCAM_CAMERA_HM0360`
+- GC2145: `#define ARDUCAM_CAMERA_GC2145`
+- OV7675: `#define ARDUCAM_CAMERA_OV7675`

+***Note: make sure to connect/disconnect the camera when the board is powered off.***
