Configuring the project

Now, we should configure our project using menuconfig. This tool is a part of the ESP32 toolchain that you have configured previously on your platform.

Open Terminal and navigate to your project directory. Then, you can type this command:

$ make menuconfig

Now, your program is ready for compiling and flashing.
