This step is not needed for the recent mainstream operating systems. But in case the Ph0xx is not recognized, try installing the drivers.

Get yourself a recent version of the Arduino IDE and add "https://dl.espressif.com/dl/package_esp32_index.json" in the field for the additional boards manager URL ( File > Preferences )

Install the ESP32 toolchain through the boards manager. Open the Boards Manager ( Tools > Board > Boards Manager ) and search for ESP32. Press "Install"

Download the ZIP file of our repository and follow the instruction described by Arduino to correctly install the library.
