1. Open the Arduino IDE, and from the menu at the top, select File/Preferences.

2. In the Additional Boards Manager URLs, add the following lines:

https://arduino.esp8266.com/stable/package_esp8266com_index.json
https://espressif.github.io/arduino-esp32/package_esp32_index.json

3. From the menu at the top of the IDE, select Tools/Board/Board Manager

4. Search for ESP-32 (the espressif library) and install it. Do the same for the ESP8266.

5. Go back to the top menu and select Tools/Board. You should see selections for both board types.
