-1. Apply **esp32-camera.patch** patch `git apply --directory="components/esp32-camera" esp32-camera.patch`
-1. Compile code `make all`
-1. To prevent any effects from previous firmware (e.g. firmware crashing right at start), highly recommend to erase flash `make erase_flash`
-1. Upload Upload firmware to ESP32 `make flash monitor`
