MQTT Walkthrough Request (video or steps)

Is there a chance anyone is willing to create either a video or step by step tutorial that demonstrates what to do after you purchase an esp32 or 8266, what to flash, and how to make it communicate with the pi? I honestly have no idea where to begin but I know it would be an extremely powerful tool to send data and receive controlling inputs upon conditions or manually. Thanks in advance!

Here’s a similar tutorial to the one above but using the DS18B20 temperature sensor:

Here’s a tutorial that publishes to the HiveMQ public MQTT broker for testing publishing:
