That’s a great question! There’s plenty of information about MQTT online, but most of it would be incomprehensible for a beginner because it’s meant for professionals who already know the basics. But thankfully, there’s the Cedalo website with various guides like https://cedalo.com/blog/mqtt-connect...ginners-guide/. This one explains what MQTT is and how to establish a connection between the broker and the client. It’s written in very simple words and is easy to understand, even for non-professionals. You can find even more articles in their website's “Blog” section. There’s also a forum where professionals would answer your MQTT-related questions.
